904 race builds

For parts, I use A&A in Indiana. They have everything you need including "race-prepped" cases which are nice. Basically you'll want 5-6 front clutch discs, (depending on what drums you have) a billet spring retainer thing, billet accumulator, 4.2 lever, the good wide bands and a manual valve body.

I have had good experiences with A&A.

The other guy was arrogant in person, and in an email with me. He will not ever get any of my money.

I met Rick Allison from A&A at the Indy swap meet years ago, he took time to explain some things to me. No arrogance at all.
