Radiator Question - Trying to replace radiator in my 85 C-10 2wd. The radiator I have in it has a core that is 28" wide, 21" tall, and 1.5" thick. All I can find is 28 x 17 x 1.5, 28 x 19 x 1.5, or a 28 x 21 x 2-1/4. Everything appears to fit correctly (shroud, brackets etc). Anyone have any ideas? Thanks for the help.

They're all correct and fit but for simplicity's sake only some combos are available as replacement, you'll have to decide with one you're going with and then locate the correct hardware.
The tank seams ride in a rubber bushing, you'll need the correct ones for the tank size on your replacement, if you want a shorter core you'll also need to find the upper brackets and a shroud.

Was really trying to avoid making all of the changes. Think I'll try a big block Suburban replacement, seems to be close.

Update - Radiator from an 85 C20 Suburban with a 454 has those dimensions.

Spectra premium CU730 radiator will fit perfect. I know because I just bought one from autozone. It was like $103 after the 20% discount code. It looks like your lacking the top radiator cover. There only like $20 for a correct one

U can see the right radiator cover in post #9
