I'm looking for the following parts.

The left brake housing, it has A508R on it. It's the early style with a grease zerk. Here is a poor picture of what I have....Brake
The first reduction cover, it's the early A556R without the cast in reinforcements. Here is a picture of what I have......Cover
The bottom radiator tank, it's A51R with the small (3/8" tall casting numbers). Here is a reference picture.......Tank
I'm also looking for an original 24 hole pan seat and a set of original straight discharge petcocks.

I'm sure as I really start working on it I'll find more that I need, but this is all for the moment.

Thanks,
Roy T. Cummings
