tremec 3550

i'm in the middle of an auto->manual conversion for my car. however, the t-5 i got isn't in such great shape. i found a guy who has a tremec 3550 with everything i'd need, plus a spec stage 3 clutch, for a grand. can i make this work? if i'm not mistaken, i can use the AOD crossmember and not have to modify it. what about other stuff, like the VSS gears? also, will i need a shorter driveshaft? can i get an aluminum one with the correct slip yoke? thanks guys.
