I'm getting ready to start cutting the floor pans out of my 64 chevelle. I have two full length floor pans to go back in. When I lay my floor pan in and mark it. How much extra should I leave hanging over from my mark? And should I try and do a lap weld or cut it to fit and do a butt weld and grind the weld down? Also, after reading the body bushing topic: Should I replace the body bushings while I have the floorpans out?

Thanks

Can you replace the body bushings right now, then do the floor pans with everything in a natural position as far as body and engine weight.

On my web site theres some pictures of a floor pan installation, don't use all the screws like I did, just a few here and there if you have to pull the pans down. This is a 69 chevelle.

If you could read through the floor pans before you start it might make it easier.

Leave as little as possible for overlap, but don't butt weld them. I think I left about 1" or so. I bet you get them installed before Rob gets his finished. :D

Hi Jason.

I'm moving along pretty slow with the floorpans. I finally got the floorpans out and ready for the new ones. I'm getting ready to order body bushings. Will I need the 20pc set or the 28 piece set? And is there a kit available with bushings and bolts? Or will I have to order the hardware set seperately? I've also seen poly bushings as well. Should I go with the stock rubber ones or poly?

I agree...I would measure between braces and then remove and replace as necessary first with sheet metal screws for mock up. then do your floor pans all with the body raised off the frame. Once the pans are in and everything looks good weld in the braces then drop back on the frame. That's what I did and it worked well.

What did you have your body sitting on when you were doing the floorpans? Did you slide the frame out from underneath? I still have the front clip on the car as well. I'm guessing I would have to remove that too in order to have the body up while I'm doing the floorpans? I dont have to have the front clip off just to replace the body bushings do I?

I did all my floor pans & New braces while on the frame. Three piece set, two sides and one under rear seat. I did the rear under seat first then remove the fronts completly, again while still on the frame. I got everything Spot & Tack weld to be pretty secure and the I removed the body from the frame. then you can get to all the tight spots you can't with frame & body together. Plus the body will stay square while on the frame. The Rear seat pan is a real bear to R&R.

Mine had the pans cut out when I bought it. The new pans were laying in place and rough trimmed. I left about 1" all the way around and welded them in. Then I crawled under the car and trimmed close to the weld discoloration with a cut off wheel. It let me keep as much of the new pans as possible and it moved the seams up into the trans tunnel and over the frame where they are less obvious.

I had my body raised off the frame about 8~10" inches with section of 4x4" wood. I placed them at all body mount points except where I was working. I did it with the front clip on the car minus the hood (I would pull the front clip if you not doing bodywork).
