wow thats a lot of work. What is the reason for the subframe being on the jig?
The tubing holding the sub frame off the table is cut to the length published for first gen body manual, I was checking the frame to see if it was bent/wracked or twisted. I discovered that it did have 1/4" twist, so I welded tubes to frame,table together & used a 10 ton jack to jack it back to speck. I also welded, ground & sanded all the sub-frame seams (to help stiffen) before removing from table. While at it I also fabricated to mount areas.
