Hello everyone. After putting off this project long enough, I have finally begun tearing into my 68 coupe. Some of previous pictures and concerns can be seen through this link . In this thread, I would like to document everything I am doing as fully as possible for the benefit of the forum.

While I can spin a wrench and do passable welding, I have never done a car restoration before. If you have any suggestions or comments, fire away. If you want me to take any particular pictures at certain points in the restoration process, let me know and I will do my best to include them.

Supporting the Body:
I do not have a rotisserie, nor the funds to buy or make one, so I thought of my own system to support the car off the ground. First, I placed the car up on jack stands, using the rear axle and the front subframe for temporary supports. I then made sawhorses out of 2x4s that run along the rocker panels on each side and lowered the car onto the sawhorses. The end result was this (picture taken after subframe was removed)

I can comfortably fit under the car using a creeper. Meanwhile, the front subframe was supported by a hydraulic jack.

Removing the Subframe:
First, I removed the drive shaft (removed 4 bolts at the rear diff, and it slid right out of the transmission). Then I removed the shifter. If I built the sawhorses higher, I suppose I could have left it on the trans, but I didn't have the clearance.
There are 4 large bolts that attach the front subframe to the unibody. The nuts are captured in sheet metal cages. If you are unlucky, these sheet metal cages are rusty and will break, making the bolts impossible to undo. A suitably sized C-clamp does work well to keep the rectangular nuts in place.

The drivers side rear bolt came out fine. The passenger rear bolt needed the clamp trick. The front bolts just crumbled apart, and 1 is still stuck in there, but at least the frame can still come off. I then lowered the subframe using my floor jack.
