57 T-Bird Distributor Codes

[Oldmics]

Well,any dizzy you put in wont be correct so I would also consider the 1957, 292 tach drive unit also.

Part #s you are looking for are

B7S 12127 A / on the housing it would read FEJ 12127 A or FEJ 12127 A2
B7S 12127 D / on the housing it would read FEK 12127 B or FEK 12127 B2

Units stamped with the "2" were usually a replacement part sold over the Ford parts counter.

Part #s were the same for Mercury engines using a tach distributor setup.
