Changing to a different gearbox - help please?
LEGACY BH5 GTB Rev A, 1999, manual.
Original gearbox is TY754VBAAA, Final Drive Ratio: 4:444, (mated to R160 Suretrack rear diff.)
Rev D gearbox is year 2002, TY574VBBBA, Final Drive ratio: 4:111, (mated to R160 Viscous rear diff)
Does this mean I would need the rear diff from a Rev D to match the gearbox?
I assume the Rev D gearbox/diff combination gives a longer top gear, and cruises at lower revs?
All gears are the same ratio in both boxes from what I gather, only the Final Drive Ratio differs.
Info obtained from these site:

and a couple of others that all agree.
