Wanted: Trade a nice 39 rear Knuckle head for a 40 & up big port rear Knuckle head

[Jerry Wieland]

Wanted: Trade only - a nice late 1938/1939 small port rear Knuckle head for a 1940 and up big port rear Knuckle head. Preferably with a 1947 date code but that is not necessary. The 1939 has no issues that I can see and I would like that in the 1940 and up head. Let me know what you have. Not for sale.

Thanks Jerry
