The larger O/D Roller Clutch requires a matching O/D Carrier & Overrun Hub.

The trick with a small O/D Roller Clutch is to not Hammer it with the shifter in D4/OD, Put the trans in D3/3rd, This brings on the Overrun Clutch & helps support the Roller Clutch.

Those fitting work fine, We use them on 3rd & 4th Gen Camaros all the time, But you can use straight fittings in a Truck.

Are you inquiring about the AFL Valve Bore repair?
