4 speed install?

[Myoldtruck]

Im changing over from the3speed manual to a sm465 4spd manual trans. This is a 2wd truck. Question for those that have installed a clutch in a 4 spd truck is how to get the trans out and in. Do i pull the trans off the bell housing 1st or pull trans and bell housing out as one complete unit. And reinstalling what tricks work well to get this all back together, im doing this in my garage. Its been years, but i use to use long dowel pins for upper ears off m21's to slide them into the bell housing on the back of the motor in the car. I already have the correct bell housing and the high hump trans tunnel to install.
