I'm not sure... I have an old 65 for sure with 45 k original miles if that would work, but not sure if you need something later... I have a second mid 60's one also, not sure of the mileage...
I would have to check my wood room stash to see what else is in there...
My son has a slant 6 with a 904, but not sure what year the engine and trans are or if the valve body would work for your application...
