when looking at that list on the message would you look for sn 021588 or 21588 i dont see any of the other sn's that start with 0 so i assume i would look at 21588

The first 5 letters do not look correct, but assuming the last 6 numbers are it would be a 1966 (straight) 450.

The other place to look up specs for differences between the 450 and 450B (besides the thread I posted) is the spec sheets at Murphy Tractor:

I believe that there was a change up on the steering clutches, clutch housing and the final drives on the "B" series of 450's. You will known once you pull the steering clutch.

Either way, a final drive case or complete bolt on shouldn't be hard to find.
