Which is best gearbox to go with a 2lt pinto in an indy?

Type 9

or

MT75

I think most use the type 9 on the pinto as thats what they came with,not sure if there are any complications with the MT75 box apart from the bellhouse being a bit bigger.

not that you should need to with a standard pinto, but a type 9's internals can be uprated with quaife bits if you ever run lots of power (or a different engine!?) they do kits to take upto 275bhp! these aren't exactly locost though....
