Bobby,
The GT6 differential ratios are 3.89:1 or 3.27:1, but you are probably
referring to the alternative 3.63:1 ratio, not usually found on U.S. market
cars,
but normally on U.K. market Spitfire 1500's.
There is no 3.73: 1 ratio differential.
The Salisbury LSD is probably a better bet on the race cars than the Quaif,
but the Quaif is better as a road car differential.
Regards
Leon
