Purchased a replacement radiator for my 85 C20. Looks like i purchased the replacement for 4 core radiator. Does anyone know if the mounts are reproduced if so who sells them? Any part number guys out there know GM part numbers for them? One last question, is the shroud different?

If you bought a 4 core that was for 81-87 C20 you should be able to find the correct parts to finish the install. They did build 85 C20 with 4 core radiators.
But if you have bought a aftermarket all aluminum 4 core you pretty much have to fab up the top mounts. I looked for two weeks and come up with nothing, so I have taken the old ones and reworked them a bit. Fingers crossed they won't look to awful.

Plastic end tank single large core. Looks to be same dimensions as copper/brass 4 core. From what I have found online the GM part numbers should be 14018579 and 14018580. Now to find some.
