a body richmond 5 speed conversion

Looks like it's their street 5-speed, 1:1 5th gear:

7031710-A Mopar 1 3⁄16-18 Spline 1st-3.28, 2nd-2.13, 3rd-1.57, 4th-1.24, 5th-1.00, Reverse-4.79

With a set of 2.94's or 2.76's in the back it would be a fun trans and friendly on the highway.

It is a fun trans. Mine took a beating behind a 540 BBC that made 550hp on the Chassis dyno and I never broke it but tore up a few clutches...

Yes, 1:1 on the final ration. 3:42 final was tall for a real street bruiser. The low gear set will give you the SLR of a Dump truck.
