Transmission Swap

I was just wondering if anyone knew what difference, if any, there was from a 1991 GMC Sierra w/ 350ci 4 spd auto trans, to a 1997 GMC Sierra w/ 4.3l 5 speed manual trans??? Other than the motor size is the bellhousing bolt pattern and input shaft length going to swap? What about the flywheel??? If you could help me out with this info it will probably save me some time if it doesn't work for some reason. Thanks

MAYBE A DIFFRENT FLYWHEEL BUT THE REST SHOULD BOLT RIGHT UP

you need flywheel, clutch set, slave cylinder, master cylinder, line for those, manual tranny drive shaft, and bolts for the clutch set and flywheel.. then you will need to wire up the reverse light switch (if you want those), and then the xmember might need to be moved, but the rubber mount can be reused... and as long as your transmission has a speed sensor, you can just plug your old plug into the new tranny.... some say you need a new chip, but i didnt have any trouble with mine....

Mine is the Standard one, so I don't think I'll have any problems with pedals or anything, just wanted to know about speed sensors or anything electrical or bolt patterns. THanks
