will a SB radiator work with RB?

Glad this thread re-popped back up.

Not that new rads are the cheapest thing in the world, but....

New Rad for my /6 '74 Duster from AutoZone was approx. $230 bucks and the /6 cools the hoped up 318 easy. A direct replacement, it worked as you would expect and like it should.

Bolt out the old, bolt in the new, hook up the hose's and add coolent.... no problems.
