Rad hoses.

O.K., these are the #'s for big block in 67-69 a-body . Bear in mind that you have to have the radiator with the top hose more or less in the center and the bottom hose must exit on the drivers side . top: Gates #20386 cut to fit . bottom : Gates#20558 cut to fit . $27.07 each

Those are the same part numbers I'm using also. I'm using a Cold Case radiator for a 67-69 big block A body in my 71 Demon. I went to the short oil filter instead of the long one for more clearance. The Cold Case radiator also bolts up to the factory bolt holes. I'd recommend installing a spring in the bottom radiator hose.
