’68 318 radiators

hello everyone,need info on replacement radiators,i have 2 1968 fury III's,,(also a 67 383 VIP)both are 318/auto and a/c,both need rad's.i have tried 2 aluminum ones,a kks and an engineered cooling products from ebay,they're both close but not quite,upper/lower hose connections are not correct,should be 1 1/2'',kks 1 3/8,ECP 1 7/16,as well as the physical build of the aluminum's make them incompatible with the shroud,they're just smaller,both are an inch narrower.if my photos go through with this post,you can see the problem is also with the top tank.the new aluminum's dont take into consideration the two piece upper tank of the original,im wondering if anyone has had this problem before and knows where to get oem brass and copper replacement's,,,thank you
