Hey Bob.
I am in the process of doing the esact same thing to my '53. I have the tranny and just fitted it today. Yes, it bolts to the bellhousing. The mount holes just need to be drilled to 17/32. I haven't got to the clutch yet, but really doesn't seem like a problem to me either. I have the clutch out and my boss has parts books, one for clutches and I should be able to find a proper one easily.

ps. hows the truck coming?
