I have a MS unit but for cost reasons, im going with the stock stuff for now. Then once i get my MS up and running ill convert.

I did the swapping the tail shaft and spedo worm gear but it was the 13b 1st gen trans. I recommend it, my car isn't fast but I just need it to get up to speed so it helps, I also wish I had a 4.30 instead of a 4.10 but it would make 1st gear even more useless.
