I don't like jacks under the trans when you're pulling an engine, as I always seem to find them with my noggin when I'm using the creeper. I'm pulling the engine in an 02 Liberty and put this together in a few minutes with some scrap from the shop - a piece of 1x2 .125 wall tubing and a couple tabs made from 2" flat bar - tubing was 34 5/8" wide. two 5/16 holes in the pinch weld area below the rocker and we're done. It's right up against the trans pan, but if I had to I could shim it up with door shims.
