At the end of my rope with this1

Show me a radiator and shroud combo in a pre-73,aluminum WP A-body with clutch fan and a hot smallblock that works without having to reinvent the wheel....PLEASE?

NO electric fans!
NO $1200 crap!
NO custom shrouds!
NO Champion radiators!
NO fabricating ANYTHING...drill a few holes,fine...
Just two part numbers that fit together and don't hit anything!

Sorry,but I've dug and dug,and can't find a simple answer!
