302 distributor differences

Hey Guys,

I need a bit of help. I finally got my 67 Stang to the point that I was ready to drop in the distributor and fire it up last night. I had isses getting the dist. to drop in. After much scratching my head I figured out that the oil pump drive is 5/16 on the engine, but the distributor fitting on the end is something less than that. It was my understanding that pre 1985 distributors were all the same? The engine is a 1982 302. Not sure what the distributor is from. I bought a complete duraspark/dist setup. Can someone enlighten me?

Thanks,

Mike

Ok, I did a bit of research this morning and it looks like the larger shaft size is found on 351W/351C and 429s distributors. My engine is an 82 302. Why would this one be different? Can I get a dist from a 351W then?
