Originally posted by Felix View PostI think I have one of those distributor conversions. It came with an engine a while back and nothing I tried fit. All I have is the prestolite V8 distributor with a mopar looking trigger system, no cap, no rotor. I tried Studebaker issued prestolite caps but ran out of options. If you find an answer it may work for me.

The Distributor Cap is: NAPA/Echlin MO-20 or Standard Ignition: CH-409X, CH-409 or CH-409T
Rotor: NAPA/Echlin MO-13 or Standard Ignition CH-303X, CH-303 or CH-303T
I have the part numbers for everything on this distributor so let me know if you need more. I could email you the entire list.
Hope that helps!

I purchased this conversion and had nothing but trouble...........the advance weights and springs were a problem, car pinged like crazy..........finally pulled it out, put back the point dizzy, which I rebuilt with bronze bushed weights, and utilized the Mopar ball bearing breaker plate. Can you spell happiness???

A conglomeration of misc. Makes and Models Distributor Parts is Never a good deal, replacement Parts and knowledge of a Non-Factory installation can be problematic.StudeRich

I have no idea what condition the one I have is in. It came with an engine I picked up for $50 and the distributor was in it so I considered it a bonus. I think I'd like to get it to a usable condition and if it turns out to be a dud I'll salvage what I can. Thanks."Goonies Never Say Die!"

Originally posted by Kato View PostMy 62 GT has the Chrysler electronic ignition conversion which I understand works because the Prestolite distributor used on some Mopar engines is the same top portion as the Presto used on Studebaker's 62 to 64, although different at the bottom drive section. I wanted to replace the cap and rotor and assumed the cap 1555503 and rotor 1555502 would be the correct parts so I ordered them. I went to install them today and found the cap and rotor are not whats on the car!
Question is now, what is on the car? I've attached some photos here. The picture of the rotors shows whats on the car at top and Presto rotor 1555502 on the bottom. The cap size is slightly different although they look very similar. The big difference is where the front clip attaches to the cap there is a notch below where the clip attaches to the cap on the one on the car whereas there is no notch on the Presto 1555503 cap.
Can anyone identify what distributor I have on the car? Were there different versions of the Prestolite distributor or did someone put some sort of a hybrid unit on the car? It was all done before I owned it. Appreciate any advice, they are somewhat worn and need replacement, if I can figure out what to get!
1) Top rotor on car - Bottom 1555502
2) Cap 1555503 no notch
3) Notch where clip attaches
4-5) Any ideas what distributor this is?
The only Mopar parts I needed for the conversion was: the top shaft; magnetic pickup & deck-plate it mounts on; reluctor, and rotor. The only mod to the Stude Presto was to remove the vacuum advance (coulda left it on as a dummy), and tap the one retainer clip hole. The Mopar parts fit many 70s-80s Mopar V8 (both CW and CCW rotating versions), and NOS is still readily available. I was even able to use the original roll-pin locators on the reluctor, to accomplish fazing.
This was all common knowledge in the 70s when the Presto/Mopar conversion was popular with Stude drivers, but has became lost over the decades. I much prefer this setup, with NOS parts, over anything from offshore nowadays.Last edited by JoeHall; 06-25-2021, 07:27 AM.
