Default Body Mount Repacement Experts Chime In

I'm in the middle of replacing the body mounts on my ride. Everything is pretty much ready to go and the old bolts are out or loose. Old bolts came out reasonably well!! My concern is the lifting of the front end without cracking the fiberglas any more than it is (small cracks around the headlights). I'm having trouble visualizing the front end lifting while I'm jacking up the sides (one side at a time). There's a lot of weight out there!!! Should the hood be off?? Is this a lift I can do on my own or should I get help?? Any advise will be appreciated.

When I did mine, I used a 2x6 jig that went under the door area; used my floor jack. All I had to do was to raise is 1/8" to get the old rubber mount out and the new poly mounts in.

I think I screwed two 2x6's together with a gap between them that the lip of the body fit into. Mine were about 30" long. Someone here probably has this and can show it to you.

Good luck

I plan to do just that, but did you unhook/remove front end bolts to raise the body?? Did you have a concern with the front end fiberglas?? All I've read says that one must raise body approx. 4" to get at the mounts.

Hi K72,
Quite a few parts (bumpers for example) are bolted THROUGH the body to the frame both front and rear. What all have you unbolted to let the body rise up? I can't really tell from your post. This IS something you can safely do, as Lanny said ,as long as everything's loose.
Regards,
Alan

Almost got everything unhooked (steering column, master cylinder, clutch linkage, rocker panels, antenna, ground straps, etc...). Tranny/driveshaft are totally out of the car awaiting new T-45rs for install. Just finished unhooking all rear bumper/brace area bolts. Have been doing a little every day. Only have the front end bumper/radiator area to unhook and then I should be ready to lift. Body bolts are out on one side, loose on the other. I'm having trouble visualizing the front end lfting when I jack up the sides. Seems like a hell of a lot of weight hanging out there!!

Yes, you need to lift the front along with the rest. When I did my '71 I used 3 jacks. Two on the sides, one lifting the rad core support in the middle. Go slow, constantly look to make sure it doesn't snag on anything. One thing I forgot on mine was the mufflers. They jam on the inside of the quarter panels, so remove them. Some other commonly forgotten items:

Seatbelt reinforcement strap in the drive shaft tunnel.
Parking brake cable.

Thanks Zwede. Whole exhaust system is already out (except headers). Parking brake cable is unhooked. Didn't think about the seatbelt retainer strap. I will look to unhook it.

The late C's are a little diffrent in the front end so I'm not sure there but I didn't unbolt much up front. Keep in mind that You can do one side at a time you don't need to lift it all at once. 4" of Lift would be great but You don't need to go that far. Keep in mind that the only way to replace the gas Line from the tank is to do this Job all over. Yes do it all over again.

I know early C3's like my 71 have solid body mounts. What are you replacing them with?

I'm using the poly kit. I've replace pretty much everything else on this car with poly so far.

My site has a list of the things I had to disconnect. I did have to lift the body completely off though. My rocker channels were in real bad shape.

Nice, which one did you get? I only thought they made one for the 73 and later cars. When I get my body off done, I want to put in poly mounts.

I'm using the Energy Suspension kit (No. 3.4126) for my 72. Kit comes with everything except the bolts. For the bolts I have grade 8 which I picked up locally. Bushings can be had in red or black color. You can get the kit at most parts suppliers. Your right, kit is suppost to be for 73 cars and newer but you can use it for earlier Sharks.

Default Try this link.

I used the method in this link: http://www.europeancorvette.com/html...eplacement.htm
It helped me big time and i was able to just remove the bolts from the front side brackets to frame without removing the front bumber. Just one side at a time and left the other side loose. Also need to remove the radiator core support bolts in the fender well also. Just look it over a few times and yes i did try to support the radiator but it seemed to do ok by itself.

Hope this helps,

Looks like I'm ready to lift!! I've unhooked the front end. One bolt was a pain in the a$$. It looks to me that the rad and support will lift with the front end. Yes/no?? The support looks attached to the body and not directly to the frame. Can someone confirm this for me??

Yes, the core support has 6 bolts to the body and 2 to the lower cross member. Be sure the cross member is detached from the frame.

Yahoooo.
Body mounts are in and torqued down. Doors close as before and the door gaps are no worse or better than they were before. Body sits about 1/4" higher than it did (aluminum spacers to poly). I can live with that!! Now I can start putting it back together. While not hard, this was a time consuming little project.

Congrates. Nothing like a do-it-yourself project completed.
