Well, I finally got the motor and transmission back in the N/A. Now I cannot get the driveshaft back in place. Do I need to pull the motor/trans back out slightly? I hope not, it ******* sucked ass putting it back in.

the driveshaft only goes on one way, theres a notch that you have to line up. Just put the driveshaft into the tranny, turn and slight push the driveshaft in. When the notch is lined p, the driveshaft will slide right in.
