That would be great! What sort of mods does he do to the box to get them to fit?

Well they're not a T56 out of a BA.
It comes with the starter motor mounted on the opposite side to what they are now, etc.
I think they were a T56 from the Mustangs if i recall correctly.
He also accepts trade ins on old T5's. Said he will pay up to $1,200 depending on condition.
The T56 has the first 3 or 4 gear ratios the same as the XR6T, and the 5th and 6th he can change ratios to suit. But of course are all overdriven.
I'm pretty sure that price was including being couriered down in a crate.
