Technical Tipo Radiator, Will a Fiat Coupe rad fit?

[Trancendental]

I did check compression:

9.2, 9.2, 9.1, 9.2

I was told the minor loss in Cylinder 3 is not a problem and is most likely caused by worn piston rings.

Emmissions and everything else are fine so I doubt the Head gasket has any issues.... at least I hope not £££
