Thanks for any help Jeff

Just went thru the same thing, napa has the bottom hose, can`t find the molded hose for the top yet, LMC might have it as there site says so, its the same for 64 to 72 V8 I`m assuming your talking of, one word of caution, Champion supplied the rad cap with your radiator, mine would not release the pressure blue out my heater core, changed my cap out with another 13 pound cap all is good.

On my 64 with original radiator, and with a 1978 Chevy
350, I used Napa hoses....

upper NBHFF284
lower NBH7165

I believe the upper is a flex hose that fit as is,
and the lower was a molded hose
that I may have had to shorten a little.

One other tip, the original top radiator hold down bracket with the rubbers will not fit, I used two lenghts of 5/16 vaccum tubing sipped under the bracket front to rear, as long as the bracket is not rubbing the top tank you good to go...

I believe I used a 1 1/2 inch X 25 inch flex for the top hose on my Chevy. Fit good

I used the upper steel tube, had to cut it down a few inches using the forward hole for the engine mount. I went to AutoZone and matched hoses up, the lower I had to cut from both ends that part number is 70558 Dayco (short pump) I peeled the decal off the top hose so don't have that I will try and find the reciept and post that P# had to cut a couple inches off it as well
