I’m in the process of installing an S10 T5 in my FD B2B. There is nothing wrong with my FD, I just wanted the overdrive gear. There is virtually nothing from the FD that can be used for such a change. You’ll need a standard bell housing (3 or 4 speed), flywheel, clutch disc, pressure plate, pedal assembly, including spring bracket. If your FD was a floor shift and you’re going with a column shift, you’ll need all the column shift linkage, including the steering column. Drive shaft will need to be lengthened. Best to find a truck that has everything you need. Another option is what I’m doing-go with a T5.
