Water Pumps

Can anyone tell me if there are any different length water pumps for a 460? I have a friend that did a motor swap but is having clearance problems with his radiator. If there is a shorter water pump available it might solve his problem. Any help would be greatly appreciated. Thanks

C8SE-8505-E is the casting number. Applications I think were early 68-69 T-birds and maybe Boss 429's.
3/4' shorter than the later ones.

I have one of the short ones for a 68 429 that is like new that I would sell if you need it. The outlet hose is at a different angle than the other pumps also.
