So, not to change the subject but i can't figure out how to post except from this thread. I am swapping a 6G72 from an 89 model raider into a 91 long wheel LS. The donor motor came from a manual tranny and is going into an automatic. I have about a 1/2" gap between the flywheel and torque converter, ugh. Anyone ever have this problem? Where can i get a crank spacer or do i have to get one made at a machine shop?? help? thanks!!
