I am about to start my L67 swap and I was wondering what trans to use I have a 98 2200 5-speed, and Im going to a 3800 supercharged series 1 I would like to keep it 5 speed. I was planning on keeping the isuzu but I read somewhere the diff suck and they have plastic syncros. I also read that I could swap in metal syncros and lsd from a storm or impulse. Some people are saying the getrag is better but I dont know what to do. Any help would be appreciated. Thanks.
