    MSD's site tells you how to measure the distance between the pump and the intake and then measure the distributor. You could probably use my oil pump priming rod and your current shaft to measure up from the oil pump and then measure the distributor.

    I bought a couple distributor gears off my friend this morning. Let me know if you want one.

    I don't know the length offhand, but while perusing the new Summit catalog earlier I noticed that Moroso sells a "short" oil pump shaft that they say is for using a big block oil pump in a small block engine. It's .125 shorter than stock. Is it possible that you got the wrong one by mistake?
