Hot Rods Flathead Generator Mount

Can anyone tell me what year this fits? Doesn't see to fit my 59AB.

 

Probaby so... on the p*** side of the case, near the front is a date code. It is stamped into the case. It will be an aphabetical letter that will denot a year.
1931=L 36=Q 41=V
32=M 37=R 42=W
33=N 38=S
34=O 39=T
35=P 40=U

 

I tried again, and it DOES fit. Thanks for the info.

 

That’s about 1942-1948.

 

42 to 48 model with the high fan mount holes.
