Man, too bad you are on the other side of the country. I am going to be doing this to my 70 Concours in the coming weeks. We could help each other! Dang!!!
For lifting, I plan on lots of floor jacks and an engine hoist. Jacks at the rear sides and hoist at the firewall. I have some Harbor Freight 6ton stands and some 4x4's, so once lifted get it high up on the stands and the wood. Put the assembled chassis onto rims (no tires) and roll it out from under the body.
I have a 5'x6' 6 wheel cart that was trash bound, I have built a crib that mates the cart to the body, kind of matching the frame. Lower body onto crib/cart and wheel it wherever.
My biggest concern is supporting the rear of the body. I have done the above lift and store on 4x4's and stands with my 70 Elco with no ill results. Tail of the car was unsupported for 4-5 weeks with the jacks and beams at the firewall and in front of the rear tires. But I am worried about something happening with the tail hanging somewhat free off the end of the cribbing. I will be trying to support the body back to the rear axle area, maybe farther, and could put a jack stand under the tail for longer term sitting, but also wonder what others have done. I was actually coming on here to post such a question. Bob and Pete have done body-offs I think, maybe they will chime in.
I am going to use Energy urethane bushings from Summit, I am buying the kit for a 70-72 Monte Carlo as that kit has the bolted bushings under the door and 4 bolted bushings at the firewall. I plan to add the MC firewall frame mounts, which use 4 bushings like a Vert, but don't know if I will get to it for this portion of the project... We will see. I have the Energy kit on my 70 Elco and have no complaints at all, so will get another for the Concours.
I'll try to get pics of the cart/crib this weekend.
Best regards,
Tom
