ZTU radiator question

[Case1951]

The radiator in my '48 ZTU was in pretty bad shape. I asked a Moline shop to sell me a replacement ZTU radiator and I had it pressure tested and it checked good.
I noticed when comparing my original radiator to this new one, the inlet and outlet are different.
Were there different radiators for different years on these Zts? The petcock on the outlet is on the bottom on the new one, not on the side. Will these radiators usually work on different year tractors?

Was like 4 versions. Same dimensions but inlet and outlets were offset or in different positions. U was the same. All should work with modifications. Pretty sure R will work also. Should be a tag on radiator from company that made it.
