I run a GV Overdrive behind an SM465 plus I swapped out the old HO72 (4.57) with an 86 DRW Cab and Chassis width 14 Bolt (4.10).

RPM's in 4th over are 1940 at 55 mph. The 14 bolt is a real EZ swap everything bolts right in with the exception of the shock mounts which need to be relocated so they are both forward facing.
