Tremec 3550 swap?

My buddy has a Tremec 3550 laying around he said I can have if I can make it work. Currently I have a mild 360 with 904 and 3.91 rear gears. To me the overdrive would be very beneficial for cruising. I did find a bellhousing that will adapt the tremec to my 360 but I'm not too sure of what clutch/pressure plate and other bits I would need to make it work. The fabrication part won't be a problem, just the bolting it all together and making it work is what I'm unsure of
