The early 216's used a roller bearing instead of a bronze bushing, and the counterbore in the crankshaft is an oddball size. Rick would either need a custom made bushing or an adapter sleeve to reduce the crank counterbore enough to accept either one of the readily available bushings sold by most vendors.

I believe it was 1937-40 or somewhere in that range.

1937 to early 1939 used a ball bearing.
Late 1939-46 used a roller bearing, but it has the same dimensions as the oilite bushing, so most have been replaced with that by now.

Thanks, Bob

It looks like that bushing/bearing (New Departure # 7109) could/can be used on many vehicles (up through about 1956 - up to 47 for GMC/Chevrolet)?
