Ant I use a GM 5speed input on my cay with the lakewood bell housing. It bolts right on. I use Allen head bolts for the little extra room they give you. I have a ford flywheel that is drilled for both Ford and GM 11" clutch assemblys. I am running a Ford diapham pressure plate 3200lbs and a GM disc from centerforce gold kit. Make sure you have the right pilot bushing in the crank. Make sure the bell housing is centered on the motor. Mine was .028 off when started, got down to .005. Alot of grinding.
Good luck Rick Lake
