BBC Radiator install issues...

[k30Dually]

Got a aftermarket aluminum 34x19 core radiator, was wanting to know if there was a difference in the lower pads?
Radiator sits about 1.5in too low. I searched but didn't really come up with anything.

It will all depend on the brand. Some may be a little smaller and not very "direct" fit. Years ago I put a Champion aluminum radiator in my big block Suburban, I had to fiddle with making spacers for the factory rubbers and I had to tweak the upper panel slightly too.
