Default Sequence to Remove C2 Body?

Our new Project 396 is finally home and on the rack. Pulled a rear wheel and inspected the brakes, tire clearances, and the bottom of the car. Looks prretty whole, no mods, etc. It looks like the paint on the rear control arms was ashault-based "undercoat" or something. Anyway, pretty dirty, surface rust, etc.

Anyway, it appears the best way to rebuild this car is to romove the body. In looking it the underside, it is not obvious as to where the unbolt spots are located. I should maybe read my "Corvette restoration Guide" in more detail, but if anyone can detail or summarize the removal process, it would be appreciated.

The one book talked about all the shims the factory uses and how important they are to maintain the body straightness integrity. It also said if he were to do it over, the body and paint work would be done before the body/frame separation. Any paractical advise there?

I have a 4 post lift, can that be utilized in the process?

Just dive in there and look everything over before you start taking things apart.
Photo document along with written notes for everything.

Check the FAQs at the top of the forum. IIRC there's a link to a checklist. If the 4 post lift goes high enough you probably can attach the straps to it and lift off the body. If you are going to keep the body separate from the chassis not hanging from the lift you may want to check out a body dolly. Your assembly manual has the body mount points documented.

All this stuff and various issues that occur and their solutions are in existing threads. The body mount bolts are usually the biggest issue if they're rusted. Air tools come in handy!

Do not allow the steering column to hang down from the dash panel or distortion to the column will result. When the instrument panel mounting bracket is removed, be sure to support the column. Remove the bolt from the coupling clamp. This is a special bolt and will require a 12-point socket or box wrench. Tap the coupling with a soft hammer to remove it from the wormshaft. The coupling is spliced to the wormshaft.

Master Cylinder - Lines Only

Wipe master cylinder and lines clean with a cloth. Place dry cloths below cylinder area to absorb any fluid spillage. Disconnect hydraulic lines at cylinder. Cover line ends with clean, lint-free cloth to prevent foreign matter from entering system.

Clutch Rod Wire Clip

Clutch rod wire clip is located directly below the master cylinder where clutch pedal rod intersects with clutch cross shaft. Remove by inserting screwdriver.

Back-up Light Plug

Back-up light plug is located behind the distributor. Caution should be taken during the removal process as wires could be pulled from their sockets. Remove by pulling connector apart.

Accelerator Rod and Ground Strap

Disconnect accelerator rod at carburetor throttle lever by removing throttle spring of cotter pin. Remove ground strap by removing hex head bolt located on the main accelerator base lever near firewall.

Oil Pressure Line Removal - Small and Big Block

Small block removal:

Oil pressure line is located to the right rear of the distributor, looking toward the front of the car. Remove by using a 7/16" open-end wrench. Care should be taken to avoid bending the copper line.

Big block removal:

Oil pressure line is located on the driver's side near the oil filter. Removal is same as for small block.

Top Engine Wires - Including Temperature Sending Unit

The following wires are located on the top half of engine or there by. Removal should be as follows:

A. Coil wires at coil, + and -, remove 1/4" nuts

B. Water sending unit, unplug connector

A. Hood - Removal of hood should be at hood latches located toward the front of the car. Remove bolts, which are located on the hood itself. After removal, complete latch assembly should still be attached to the inner fender wheel skirt.

B. Radiator - Remove radiator inlet and outlet hoses at radiator. Remove transmission cooler lines, if so equipped. Remove shroud to radiator support screws. Rest shroud on engine fan. Remove radiator upper support bracket screws and carefully lift radiator from vehicle.

Removal of these nuts will allow wires to hang free. There is one additional wire connected at the base of the starter (ground). By removing the outboard starter support bolt, this wire will hang free.

Looks like a complete list. Make sure you remove ALL of the rear bumper braces. There are two inboard braces between the frame and the body that the rear bumper attaches two that I missed. I ended up cracking the body.

This is a long and expensive road to travel down. I would make 100% sure you want to go down it before you start taking the body off. Seems like you bought this car and it hasnt been run for a while. The body doesnt look too bad from pics. I would seriously consider going through the brake and suspension with the body on the car....you can get the motor running and get it on the road for a year or two THEN take the body off.

I 've been down this path and unless you (a) have a nice size shop (b) retired (c) lots of discretionary cash....I wouldnt do it.

If you have access to a welder, I would attempt to weld a body dolly based on the frame specs from the AIM--much sturdier than wood. If you go the wood dolly route (plans are on the forum somewhere) I would look into increasing the vertical height of the dolly. The wood dolly puts the body at about standard height but it is impossible to get under.

Good luck. This forum is a great source of info.

Your points are super valid. I looked at that list and contemplated all the work after the body is off, and...it is a major chore.

So maybe time to step back and consider what can be done with the wheels off!

You're welcome. There are several of us here that have done body-off restorations. To me, it's the only way to get the results I want. Jump in with both feet and don't look back. If you get stuck, I'm here to help. Maybe a road trip to Utah is in my future. I had a guy fly me to L.A. to help him with his Cobra when he got stuck. 3 days later he was driving it with a big grin.

Larry,

Yes, you can lift with a 4 post lift. I did it, worked real slick. See attached photos
