Beautiful truck.

I'd say 95% of all parts stores / catalogs will tell you to put a piece of bulk hose on it (which will want to kink some). I've found short hoses with a formed 90 in the past but that's almost as bad as a straight piece because you're forcing the hose to go against it's shape.

I got mine from Summit but I don't recall the part number. If I remember correctly there are two different water pumps, long and short, but the hose is the same. You just need to be shortened if you have the short water pump.
The bulk hose always seems to kink in that application.
I bought one for my Chevelle SS from Ground Up.

Actually, now that you say that I think that's where I got mine. I bought it for the 396 in my Chevelle. It's been a couple years..

I bought one from Summit last time I was there.

In the past, I have just bought a formed heater hose with bends in it, then cut out the part that I wanted to use.
