Gents,
I'm replacing some old parts on my 66', and just ordered a new accelerator pedal from NPD. It's the correct part for the 66 with the two holes for the floor mounted studs. But, like the pedal I'm replacing, the post next to the hump sits a bit below the carpet, and I'll be damned if I can get the pedal to snap over the stud !!! The old pedal keeps falling off, and I think the new one may do the same. The stud isn't loose and I don't think it's sunken into the floorpan. That pedal is not an engineering marvel and maybe it's just a bad design, but do any other 66 owners have the same problem ?? I'm thinking I may have to throw some washers behind the stud to raise it up a bit, if there's enough thread length to handle it. Anyone out there that has resolved this...other than using duct tape ??? ;-) Besides being a drag having the pedal fall off,,,it's downright dangerous !!!

If your carpet is new, you might try removing some of the jute backing on the carpet in that area, should allow the pedal to snap on.

I was a kid when I got my 66, and it didn't have the studs anymore. so a buddy and I replaced it with a 69 pedal assembly.

thanks for the replies guys... I did manage to get the new pedal on, but it's REALLY snug and I have to kick down the idle at times due to it pressing pretty good on the linkage. The carpet is not new, but I think I'll need to pull it up and ,as you suggest, pull some of the backing material out. I like the idea of replacing the pedal / linkage too, that 66 is a poorly designed mechanism. I also think I'm not getting full throttle because of the pedal...that I can adjust. I've gotten pretty good at just pushing on the linkage with my foot ;-)

I'd have to agree with you in questioning the design. Not so much the "snapping/stud" issue as the doubting "full throttle". You don't respect the free motion range as idle to WOT, instead you push like there's no end at all. Really hard on carb throttle shaft bushings and linkage.

Here's what I discovered, for what it's worth. I wanted to replace the original studs with some new ones, which I ordered from one of the parts suppliers, Year One, I think. The new ones looked like the old ones, except they were shorter, and when I tried to use them, the pedal would not snap on or it was too snug like you described. I ended up cleaning up the original ones and using them, which work fine.

So just beware that there are studs out there that are too short. If you're interested, I can measure my originals and the replacement ones I didn't use. Let me know.

66Malibu ... please do measure if it's not inconvenient. I was going to maybe order spares from NPD,,but if they are shorter, that will make matters worse.. Thx

Stickman,
The repro part from Year One measures 7/8" from the tip of the ball end to the bottom side of the hex nut shaped base (where the threaded part meets the hex). In other words, if the stud was screwed into the floor, it would stick out 7/8". I didn't get a chance to measure the original one on the car, but I'll try to get to that tomorrow night. I know it's longer, maybe 1/8" longer. Anyway, this will at least tell you whether or not you have the too-short repros, or taller originals. Seems like I tried to use a bunch of washers underneath these repros to make them taller to stick up through the carpeting, but just couldn't get it to be satisfactory, so I cleaned up the originals and used those.

Hope this helps.

Malibu... thanks for taking the time to check your accelerator studs. I believe mine are original...they look like they've been around for 40 years. At least I can measure and see if they are as you suggest. I'll have to pull up the carpet to get a good look a them, and to cut away some backing if needed. When I'm able to get both studs secured, it applys too much pressure to the linkage and I end up with a "poor mans" cruise control. The engine idles at 2K, so I have to settle for one stud and a floppy pedal in the meantime.

Heck nobody uses a pedal !

Just step on the metal end of the assembly !

 

[Chris R]

Thats what I do. Mine kept falling off so I just left it off.

Is your carpet new? I had this problem when I installed the carpet on my 65 442. Problem is when you install the carpet, you really need to press it into that corner so it really seats into the groove. Otherwise, it will pull away and you're pushing down on carpet that has bowed out and it will cause the pedal to pop out.

I was aware of this problem when I installed the carpet on my 66, and I had no problems. It's not fun, but you can probably pull the front seats out and re-set the carpet and it will be fine.

Sandy... I have had to do that...when the pedal falls off !!! Seems kinda barbaric to be pressing on a hunk of metal to make the car go. I have seen several 66's for sale...fully restored....without the pedal. Fully restored,,but even they can't figure how to get that pedal to stay on !

[ Corellian ] The carpet is not new. I'll probably just have to pull the carpet back and see if there's some excess insulation I can remove to expose the second post better. It stays on one post OK, but tends to slide off the linkage. I used a cable tie to wrap around the pedal and linkage...works great ( for now ) Cable ties and duct tape...two miracles of modern science ;-)

Full throttle was a big issue on my cousin's 67. He's got a 327 with a torker and a 650 DP. We had to remove the throttle arm under the hood, V cut it (on the firewall side), bend it and weld it. Now it gets full throttle and the free play that was always there is gone.

Is the 69 assembly a bolt in along with the cable etc?

Thanks,

David
