radiator too big

[Rockinlittle325i]

So I got a northern radiator, and it turns out that its too long

I want the extra cooling, but to fit it in would require cutting and boxing the frame.

What do you guys think?

before i cut and boxed my frame i'd consider removing the clutch fan and replacing it with an electric fan. Then you could go with a thicker radiator

What makes you think you need a bigger radiator than factory? My S50 swap car ran nice and cool with a little M42 rad in it.
