Does anyone have a water pump (spin on type) in the box or on the shelf somewhere? I need a measurement. From the end of the threaded "nose" (where fan clutch spins on to the shoulder where the pulley bolts on.
I'm working on a project. Actually, I'm just thinking about a project.
Thanks in advance.

ok, bro, what's the project ?
Love to see photos of what you end up with!
Im thinking of going the full aluminum radiator route with wolfie. Something HD or racing grade. Ill be going electric cooling fan as well.
If you aren't running A/C, and haven't pulled the condenser yet, there is probably a good amount of room on the front of the radiator in the core support.

I pulled the viscous fan from my heavily modified euro 635 and an 83 533 and added a switch for control on the aux fan. As long as I turne the fan on , never had a problem. It won't take much for an added electric fan to keep it cool
