1940 ford super deluxe

[arthur]

i'm considering replacing the distributor with a rebuilt on my 40 ford v8. the heads on the engine have an A on them so i think its the original engine, but the distributor and coil are seperate and some illustrations i've seen don't match up..my distributor is a 2 bolt and the cap isn't a crab type, but a round with two flutes for the s/p wires...???
