I've seen distributors listed for manual trans and for automatis trans. What is the difference?

Can't say as I know for certain, but I'd guess the mechanical advance mechanisms are a bit different.

I think its just the advance rate, as I think Dnult(Dave)was tring to say.

You took the words right out of my mouth. :D

The vacuum advance can calibration is frequently different also. graemlins/thumbsup.gif

Thanks guys!
