1988-up \"new style\" trucks and 81-87 C/K owners.. Anyone that owns both of these vintage trucks, would you be so kind as to just take a glance at the radiators in both, and see if the '88-up style could be made to fit with a little work in the '81-87's? Same or similar coolant inlet/outlets, etc. Manual trans already, so tranny cooling doesn't concern me either. I know the 73-80 trucks used the same radiators, so if you own one of those, that would be a fair comparison to the '88-ups as well... I know sometime '88 or later GM went with AL radiators (they must have right? : ) and I like the idea of adapting one to my earlier truck for the better cooling. I already know the HxW difference is supposedly -1" either dimension on the newer trucks if already using the "standard" height '81-87 radiator, but as long as the mounting system is the same, or adaptable, excluding the fan which doesn't matter, I think it would be a good swap, and a heck of a lot cheaper than a non-stock AL replacement. Thanks!
