They should just clip right in to the factory holes on the inside lip of the window opening. The fuzzie one goes on the inside, the rubber squeegee type one goes on the outside of the window. Just take the long rubber ones and match 'em up to the holes and then clip 'em in. That is if all the clips align, I had a set for a 65 where the rears didnt line up so I had to remove the clips and reinstall them in the right locations.

good luck

 

My 66' has the original fuzzies on the outside and the rubber on the inside. I am pretty confused now.

I thinkl J70chev got it backwards. The fuzzies go on the outside, rubbers on the inside. Roll the window down and see if it goes low enough to get the old one out. You might have to pull the door panels to lower the lower window stops. This lets you drop the glass into the door further to aid in the replacement of the fuzzies. Raise the stops back to where they were when you finish. Good luck,
Roger

 

My fuzzies are on the inside,rubber on the outside.
Never seen them the other way

 

Rubber on the outside, fuzzy on the inside. Always.

The rubber is there to keep (most of the) water out. The fuzzy part wouldn't do a very good job of that. I have to assume that on those cars with them installed backwards that someone replaced them in the past and did it wrong.

 

Gotta agree with Rich on all counts

 

I have repops on my '67 and the fuzzies are on the outside. They won't fit any other way. The inside piece needs to be shorter. Mine fit perfect with the fuzzies on the outside.

 

I hope you put the plastic water shield behind your door panels because those fuzzies wont stop one drop of water.

 

My 64 Conv new window felts have an anti window rattle spacer pop riveted on them. I didn't know what it was for. I asked re-pop by e-mail. They got right back to me with the answer.

A screw on each end also holds on the felts.

My original fuzzies are on the outside, rubber on the inside. But I have a 71-72.

Now ya got me wondering, not questioning, but wondering.




Edit:

I just looked at a few original 70-71's and some other brands from the 60's and they have rubber both sides. The only difference is the shape. In all cases the inner is the "V" shaped rubber w/ felt against the glass and the outer is the single rubber wipe edge.

Now I'm wondering if they put different ones on the post cars. My "V" shape in on the inside, with an all fuzzy on the outside.

I know it dosen't do much to answer the question, but maybe the shape will help, at least that does seem to be consistant.

 

It makes sense that the rubber would be outside to keep water out, but I think it was the fuzzy. I remember 20 years ago when I got my 68 z/28 RS it had the optional chrome running on the top of the doors where you rest your arm and the fuzz was worn down and needed replacing. A friend said he had some in his attic he bought for a car that he had sold. When it showed up it was brand new chrome and fuzzies factory attached. That's Camaros, this is Chevelles, I know.
Now if we have the rubber on the outside wouldn't we have a greater chance of scratching
the window with sand and dirt when we rolled it down? The fuzzy would "absorb" the grit and rubber might hold it againist the glass.
Maybe they varied from factory to factory...........does anybody know for sure?

We are talking about, at least I am talking about, 1964-1967 models only. The 1968-1972 models used a different set up.

The rubber on the outside doesn't actually touch the glass so it would not rub against the glass as it goes down if everything is adjusted properly. The rubber seals against the base section of the window assembly to seal out wind and water when the window is fully raised.

Concerning Repops brand not fitting one way: that doesn't really mean much, Repops are well known for not being correctly made. They are some of the better looking sets available and look more correct to original when installed correctly but they rarely fit correctly without a little help. Many people, myself included, have had to remove and reposition the retaining clips to make them work. That doesn't mean I put them on backwards, it means they were manufactured wrong. Never ever trust that a reproduction part is made correctly! No offense intended, just the facts.

And as mentioned above, the hard plastic block at one end of the long rubber ones for the doors are intended as a rub block. The block is to go to the outside rear edge of the window opening and registers against the frame that holds the glass when the window is fully up. This keeps the glass from vibrating. Also, this block has a small countersunk hole in it and should have a small screw through it to attach the rear edge of the rubber strip securely to the rear edge of the door.

Folks, if you have any doubt about which goes to the outside, just visit your favorite old car junk yard and check out the original GM window felts on any early (1964-1967) GM A-body. Rubber on the outside, fuzzy on the inside. Always.

If it will help, I post some pictures from my original body manual which also show which goes where.

 

This is what i found in the body by fisher manual for 66

A-07-17-39 and 67 styles 'j' strip inner- pile outer

A-11-69-35-55-65 and 80 styles pile inner-rubber outer



p.s other Gm models also have both ways listed

 

I am also assuming we are talking only about 2-door hardtop models. I honestly have no idea what window felt set ups are used on 4-door sedans or 2-door sedans (cars with window frames and b-pillars/center posts). I have a 4-door parts car which I could look at this weekend.

 

I'd say you're right Rich. As I stated, all the cars I looked at had the rubber on the outside, but all were hardtops. It must be just the post cars that have the full felt on the outside, between the uprights.

I think Roger has a good point as to why their use on the outside, certianly explains things a little better.

Love to learn new dribble I'll probably never use

But not even the fuzzy strip if attached to the outside edge would touch the glass itself as it goes down.

 

I feel this should settle this once and for all. This illustration is from the Cheverolet Body Service Manual for 1965. In the text this illustration applies to ALL BODY STYLES. All 64-67 Chevelles used the same windowfelts.

 

Rich,

all I can say is thanks!! I am impressed.

Are you really sure Rich?? I don't know...I am still skeptical

Only here could such a simple thing get two pages worth of responses...thanks for sticking with it Rich

 

Details Mike!!!!

Leo, I think Mike is joking (maybe you are too!).

The picture I posted isn't appearing right now, my website hosting seems to be having some difficulty this morning.

 

Yeah Rich, Mike and I do this a lot. When you see his car in person, you will know what I am talking about.

 

Well guys, I'm not one to give-up so easily either

I concede that 64-67 hardtops/sedans are exactly like Rich's illustration. But I must stress that you should consider Roger's explanation of the "felt brushes" ON THE OUTSIDE to be fact for some models later than the stated 64-67 years.

Not to do so may be embarrassing at some point in the future. Just a heads-up.

And though long and tedious, this post was insightful in more ways than just correct weatherstripping, and I thank you.

I think we've been stressing all along that the topic as discussed was encompassing 64-67 Chevelles only. The original topic is concerned with a '66 Chevelle so it all fits. I wouldn't want to make any statements about 68-72 since I have no idea what type of set up was used on those years. If I implied along the way that this info applies to 68-72 as well let me definitively make myself clear: I'm not talking about 68-72.

I am also aware that other Chevrolet models of older and newer vintage may have used fuzzies on the inside and/or the outside, but again, we are talking about 64-67 Chevelle ONLY (at least I am). I guess I don't see any point of confusion.

The resto forum is so darn fun! Where else can you have a multi-page discussion on windowfelts! The performance guys probably think we're nuts!
