Hi I'm new to this forum. I'm working on a 1967 coupe we bought new in 67 last drove in 73. The manual shows the car on stands to remove the diff assy. In order to do this safely [for me and the car] I want to build stands similar to those shown. I do not want to build them higher than necessary and really don't want to have them turn out an inch short and have to start moving the car after I have the diff assy on the jack. Does anyone know the proper height from floor to top of wood pad? Thanks

Here is a picture or mine as it sits today. Its exactly 36 inches to the center of the rear bumper off the ground. I added the picture to the below image upload and am not sure where it will end up. I would be very interested to here how your dropping the rear end goes.

One other thing. You are going to have to disassemble the emergency brake actuating arms. Try to take some photos or draw a diagram before you do this as it can get quite complicated. The actuating arms (resembles a spider) is welded to a shaft that in turn is bolted to the cage. Unbolt this actuating arm assembly from the cage because you don't want to bend it.

All you have to do is scoot under the diff and measure from the bottom plate to the top of the cage; there is plenty of access to get a steel flex ruler up there. Then add the mount that your jack will need to roll. Ten add 6" for good measure.

Removing the rear suspension unit is not all that difficult, except when it comes to removing the nuts from the driveshaft flange...those bastards are on there TIGHT!! There are shims on each side of each of the suspension mounts, so keep up with what came out and from where.

The rear suspension should balance fairly well, however, I would have someone stand on both sides as its being lowered. Once out, it will be top heavy and will want to flip on you. Unless you have a major problem with the rear end, I would NOT drift out the shafts for the two arms...lots of shims and bearings to re-align if you do.

You will have to remove the exhaust pipes from the mufflers on back. I would use a 4x4 piece of timber to span the "frame" area with a separate jack under the timber. This will help raise and lower as needed. You can lower the rear suspension (with wheels on the hubs) down far enough to where you know everything has cleared. Then raise the jack with the timber to the point where the rear suspension just rolls out...but keep the pressure under the plate so that it doesn't flip on you!
Whatever you do, make certain you replaced the gasket on the rear end cover, and use PermaTex....I wouldn't trust the silicone stuff!

Good luck!
