Ive got me one of these here blazers , and i just cant seem to find the bell housing bolt size? Gonna get me a rebuilt 4l80E to put in it, and the next thing is its a 4x4 blazer but the transmission is 2wd any idea on how long or short the drive shaft will have to be? the bell housing bolts are the ones that hold the tranny to the engine right? I need to know the size or where i can order off the internet please people i wanna see this thing move thanks for the help! btw google has been no help for the past 2 days..
