I am in the middle of doing a new clutch for my corvette and had to make a fixture to help with removing the rear suspension cradle. A clutch change involves removing the complete drivetrain from the engine on back. I borrowed a fixture from a friend that mounts on the engine hoist that supports the transmission/rear end assembly but it wouldn't work until the rear subframe was removed. To make it easier to align things during the reassembly process I decided that the subframe fixture should include a parallel link system so the fixture stays vertical when raised and lowered. I modeled the basic engine hoist frame to make it easier to design the linkage. The new parts are shown in red.
First step was to drill the 2 pivot holes. The hole in the main support member was hand drilled.
The other was drilled using the mill.
The lower hole is original, used for attaching the chain, the two upper holes are for the 2 different fixtures.
Most of this will be built using materials left over from other jobs but I did have to buy some flat bar. First step is to cut two pieces to length that will be the lower links.
Setup for drilling the 4 pivot holes. No close tolerances required so a simple stop was used.
I needed 4 spacers so I found a piece of an old barbell to use for raw material. Just a drilled hole and parted to length.
Nothing fancy required.
