Big block + large rad + Mechanical fans = what fits?

I have a "bolt in" aluminum rad, pretty sure is a 22" that has 3 - 1/2" rows, I cannot cut and reweld at this time or I would.. but that would only gain 3/8" or so..
28x19 crossflow griffin, 2 row 1 1/4" tubes, w/ 17" factory steel fan, 1/2" alum. spacer. didn`t need to cut the opening on a 68 fastback form S.
