Bianchi - the T5 I have is brand new, made in 2010 , the 86 box was WC and this one is I hope a bit stronger than the original, presumably the input shaft is the same as the 86 mustang V8 so they bolt straight in.
Iachella - yes you are exactly right, if you put an adaptor plate on a non motorsport box the input shaft will be too short, also all T5 input shafts are bigger and have a longer sleeve for the clutch bearing. We are cutting the back off an Alfa bell housing and welding a plate onto that. My engineer has done this sort of thing many times, here in NZ we don't have the resources you guys in the US have so we tend to build these things ourselves. You wouldn't believe the range of cars running around here with Toyota box's.
Using Bianchis adaptor plate would be less hassle though. My car already has a Ford pressure plate, , paddle clutch, toyota clutch bearing with custom mount so its all different anyway.
Before I ordered the box I did some research as was a bit bothered about stories of T5's breaking while racing. Took me a while to realise that these were US stories and they were talking about V8's drag racing with slicks, big torque and locked diffs, the gearbox is the weak link,
While my 2 litre Alfa has the same power has an early mustang V8 it will never have the torque and the weak link is traction of the tyres, 205/50 racing tyres, you wouldn't want to go wider, so unless you get a very early box or one made for a 4 cylinder I don't thing breaking will be a problem. However you want a V8 box to get the right ratios.
