I will try to get this correct! I purchased a1938 81a 4 door deluxe ford. It had a hitch so I sent the distrubitor to bubba . I reinstalled this after noon and I would like the world to know it starts and runs great! Oh, I went back to a 6 volt battery. Thank you for a great repair bubba!!!I want to change the engine oil and not sure what to use. I was told it had 15-40?? Thanks to all!graderman
