This is an Offenhauser 3605 Starter Change over intended to fit 1949 and up Oldsmobile engines. The adapter moves the starter to the right side of the motor to eliminate interference with 1935 and later Ford steering boxes. The housing is in good shape, and all the threads are good except for one which is clearly marked. The threads in that hole are enlarged about 1/2 way down, the bottom half of the threaded hole seem to be good and tight. $000 plus $000 shipping lower 48 only. Payment with Pay Pal, or cash when picked up locally. SOLD SOLD
