If he is Ok with generic there is always Champion. There was a comprehensive thread on them recently that you might be able to retrieve. I used one (22") in a 65 318 dart & no leaks and no fitment issues other than having to redrill 1 hole in one of the side flanges. tho my 318 did not test it's cooling capabilities even with it being a 2 core but the inner tubes/cores looked very generous & I didn't see a problem anywhere. Some reports of them being warped slightly so check that right off the bat when you get one & a guy on here sells them with an unconditional money back guarantee. Cant beat that. Just have to drill some holes to mount the shroud. EDIT it was $189 to my door from eBay (cant beat that) & all good till a drunk driver took me out
