Yep, 69 will be a short pump, you have a long one - if you swap anything, you kinda have to swap all. I'd look for a different radiator hose and use the long version of the pump, otherwise, brackets, alignment, all that stuff is out the window. It's a lousy problem - I am in the same boat, trying to decide which way I'll go as well while I consider my engine options. Would really just like to find an original 72 truck 350 that hasn't been bored out a few times already
