Rotowrench has it and it;s been done many times. The clutch will also depend on the transmission. Most passenger and light trucks in the 42/48 used a 9 .10 clutch, but the 9 is different than the early (' I think the 48 up 9 was actually a 9 1/2 as the bolt pattern is different. . But the fingers won't fit the early pilot shaft with out modification. I never use the early transmissions, so I'm not sure about this. hOwever the conversion has been done many times, Use the head gaskets for the style heads
