It Dont Fit!

[rambler]

OK,, finally working on my 72 again,, I hit a deer last year,, and finally got all (new to me) parts (mostly from teeitup, thanks Randy) and got the core support and fenders etc on.. started to install my new 4 core radatior ( with new uppers and new cushions.. but old lowers. I swear they are still 4 core lowers as the old support I got had AC with it,, well the radaitor cushions fit nicely in the upper supports (new) but the lower little tight on the sides and the whole radatior is about 1/4 to 1/2 higher than the core.. ( I hope this wasnt a 67 core? well now what are my options? trim the cushions? but they are new and the raditor is very expensive to risk , or grind off the lower supports and order new ones? of course I POR15'd the entire core support? I'm kinda frustrated right now.. any ideas? I dont think just bolting and tightening the bolts will work... am I missing something?
