Fitted my V12 SIII with the Borg-Warner T-5.
The kit came complete with a new Bell housing included. Fit perfectly
and after the engine overhaul the car fairly snarls down the road. The fifth gear makes a big difference.
Like many cars of that era, the tach would be pushing 3000 at 60-65 mph but with new box I am turning it over at just 2000 rpm.
Drive safe.
