DaveV, Thanks for posting the info. That bottom hose number is what I came up with and plan to pick it up Monday for my coupe with a 261.
I had to use the Water Pump Adapter and an old style water pump to get things to work in the coupe and I needed the radiator bottom outlet for 1 3/4" and the pump 1 1/2". Needless to say I won't need the reducers I alluded to in my above post but its always an option.

...the Carquest #21615 you listed crosses to a NAPA # NBH 833

Hopefully this will help someone else without them going bonkers like I have been looking through rows of hoses!

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
