Old Mopar Distributors
 

I was digging through some old distributors and wondering if knows what years and engines these are from ? Chrysler #20988085 / numbers under the above are /ibm4108A246 ! Chrysler #3690201 / numbers under the second set are 32.9 ! These both are mech tach drive, and have a cute little oil port with a spring loaded cap ! Any Idea's ? I thank you in advance for any help !........John

I believe the 3690201 to be sold by Mopar via whatever the direct connection was called at the time. It is for a RB block. The same part number but 200 was A block.

From what I could find on the other 2098085 (less one of the 8's) is also for a RB block but was a marine application. Since some marine engines are reverse rotation perhaps the advance direction may be different from the other.
