Running a GM transmission behind a Ford engine leaves the converter pilot sitting in a crank register it was never machined for. This adapter bridges that gap, sizing a GM converter's pilot to the 1.375 in. register in a Ford small block or big block crankshaft so the converter centres properly instead of running out of true.

• Adapts a GM torque converter to a Ford small block or big block crankshaft.
• Sized for a 1.375 in. crank pilot register.
• Centres the converter correctly in an engine and transmission swap.
