I did round the OD. I probably just transcribed 3rd gear wrong. I was looking at a chart with a lot of numbers. I did round the OD. But the rest of it is correct. And Clark 204VO should bolt right on to his 1946 clutch housing , but not on his 1952. I have a 1946 GMC 1 1/2 ton with the 4 speed. A previous owner replaced the 236 with a 302, which it really doesn't need. I have 3 550 GMC's with 370 V8 engines. I drove a 550 80 mph down hill 50 years ago. I don't care to go that fast any more in an old bucket of bolts. But I do still drop of of hills 80 MPH in our Cummins powered Internationls. The speed limit on IH 10 here is 75 and they overlook 80.
