I installed a Pro-5.0 shifter into my Camaro a week ago or so. During installation, I went ahead and removed the stop bolts before I put them in. THe big reason behind this was that when I was trying to figure out how to set up the stop bolts, I couldn't figure out the proper spacing. I didn't want to push them in too much, but I didn't want to over-rev the tranny either. So I consulted several boards on the net, including LS1tech and LS1installs.com. Basically its too different stories, and people say you do, and people say you don't. Some people say the T-56 has its own internal stops, and other people say you need to run them or the transmission will overshift and blow up. In the end, I decided to leave them out because it seemed like their was more of a chance to screw something up by leaving them in. What do you guys think?
