#2 body mount replace with pics
I am in the middle of a frame off on a 1974 coupe started mid Sept 2014. Struggled to find good info on body mount replacements so I thought I would post how I did it. I changed both #2, one #3 and both #4. This is on the #2, will show the others later, hope this helps folks.
https://cimg4.ibsrv.net/gimg/www.cor...9430312f7a.jpg frame is ready for the body, hopefully by end of summer body will be done https://cimg5.ibsrv.net/gimg/www.cor...e144c70cb4.jpg The frame before Here are some pics of the corrosion in the #2 area, as you can see they definitely needed replaced. Rest of rockers and birdcage is rust free https://cimg2.ibsrv.net/gimg/www.cor...82bf1a6cad.jpg the bottom of #2 https://cimg3.ibsrv.net/gimg/www.cor...83feb4f24f.jpg Top behind kick panels https://cimg6.ibsrv.net/gimg/www.cor...8d2aeae070.jpg These are the repair kits I got from Zip, they slide up from the bottom and are welded in place. The front hole lines up with the #1 body mount hole, if you secure the repair kit with a bolt to the #1 body mount it helps insure the #2 hole will line up when welded, I will show pics of this https://cimg4.ibsrv.net/gimg/www.cor...ffa766f0e4.jpg The part that says LH slides up from the bottom in the #2 hole, the front hole is the #1 mount I talked about. https://cimg5.ibsrv.net/gimg/www.cor...30ab9ecdcf.jpg This welds up to the bottom of the rocker channel Next pics show the rusted out part of #2 area that is cut out, this is where the repair kit slides up into from the bottom https://cimg4.ibsrv.net/gimg/www.cor...25eb44f3ab.jpg Used a sawzall cutting from the bottom, the area to cut out goes from wall to wall of the area behind the kick panel https://cimg6.ibsrv.net/gimg/www.cor...5ccc3e1c92.jpg cleaned and ready for test fit Next pics show the repair kit installed, slid up from bottom and welded in place https://cimg4.ibsrv.net/gimg/www.cor...0ed6149840.jpg Need to remove the lower door hinge bolts to get the kit to slide up https://cimg5.ibsrv.net/gimg/www.cor...c70a2fd668.jpg I put POR15 on the birdcage structure before I installed the repair kit https://cimg6.ibsrv.net/gimg/www.cor...a6b509fe7f.jpg looking up from bottom. The metal has been metal prepped for POR15 https://cimg7.ibsrv.net/gimg/www.cor...883cb2569e.jpg You can see the bolt installed in the #1 hole for alignment Next pics show after I applied the POR15 and completed the repair https://cimg8.ibsrv.net/gimg/www.cor...91f528b072.jpg No more corrosion and this is stronger than the original part of the body https://cimg9.ibsrv.net/gimg/www.cor...4fe24821a9.jpg I had to use 2 bolts from the hinge mount with a piece of metal under the heads to hold the repair kit against the birdcage structure before welding https://cimg0.ibsrv.net/gimg/www.cor...3b299f13f3.jpg #1 hole lines up so #2 will also. I measured the frame mounts to confirm the body mounts https://cimg2.ibsrv.net/gimg/www.cor...3d8e92ae5d.jpg Not sure I explained everything as understandable |
Very nice job and write up! :cheers:

Hi s,
Very nicely done! The pictures show pretty clearly just what was done so I'd think they'll be helpful to people with #2 body mount and lower hinge pillar troubles! Good Luck as you continue! Regards, Alan |

I also did this repair using 3 piece rocker channel inserts made by Caledonia Corvettes in Michigan, for each side. I believe when I did mine the instructions said that the A and B pillar sections were inserted, then the center channel installed and welded in place. Next the body lowered onto the frame, shimmed, and bolted back in place checking for proper door gaps. Then last the A and B inserts were welded in place.
Looks like your A section was welded before the body was installed. It's been a while since I did mine, but from what I remember, I thought I would just mention how I did it. Your work looks good. Good luck with the restoration. |
