Got some aggravating news yesterday after starting what I thought was going to be some finish paint work. I was in the rear wheel wells getting ready to put some paint on and after pressure washing the wells I noticed the rear body mount on the drivers side looked a bit funny. I started picking at it and it looks like one of the P.Owners tried to patch a rusted body mount with a cheap fiberglass putty or something.     I didn't pick hard but, the crap just started flaking off what was left of a rusted body mount. So, I looked at the other side and sure enough it was the same kind of thing.
My question is this...Can the rear body mounts be replaced with out taking the body completely off the frame?

The cushions can be replaced by loosening all of the mounts, and carefully raising that side of the body up a bit.
If the cage(body), or stand-off(frame) is the part that's rusted, those need to be welded on the frame, and riveted on the body

Thanks Joel for the reply Joel. The number 4 mounts (the ones above and behind the rear tires) are rusted through on two of the sides on the drivers side and on the passenger side. I will replace the rubber cushions as well. Man, just when I thought I had most of the tough stuff done.fedexbicman762007-07-15 13:18:48

I started there and ended up with pulling the body off to fix the rest of the mounts that were just as bad. Not trying to scare you but if you plan for the worst and if it ends up better you will be happier. Either way, it isn't that bad of a job.

Thanks for the vote of encouragement and the lift guide Brian. I am looking into some help on this one. May have found a local person to help.

I'm lifting the body on 79 right now. I should say I made an attempt at it tonight. Thought I had everything until I realized I forgot the rear bumper Ouch duh! I printed out redwingvette's checklist and missed step one on the copy paste. My body mount bolts were real bad up in the front rockers and the frame has a thick coating of road grime/grease . 
The lifting harness I bought from corvette America is nice but it's really long as I'm using my shop crane to lift it.
I definately could have gotten away with using the 5000 lb cargo straps I had acquired from work in place of the lift harness. Whenever my new camera I ordered from amazon arrives I can post pictures.

Sounds good. I would like to see the photos of the lift. Thanks and hope the next attempt goes better.

Well I gave up on using the shop crane. You could definately get the body up high enought to change out the mounts using it. And don't buy the body lift harness it's a waste of money. I ended up getting a chain hoist from harbor freight and from 9' I still had to wrap the body harness 3x around 2x4's to get the body high enough to clear the gas tank. That thing is way too long. You could easilly use some ratchet straps and do a much better job. What was odd is that the only rust I have on the frame is at every body mount point. Two of them had to be drilled out they were rusted so bad. One was almost completely rusted through the bolt and the rest of them weren't much better.

Jason, thanks for the tip on the body harness. Sounds like I may be in for more work than I was thinking originally then too. I will find out when we get the body lifted on my mine. Glad you were able to get yours lifted and taken care of. Let's hope everything else goes easier from here on out now.
