I'd literally say you're not wrong Mike - just find it amazing that none of the manufacturers seem to make an alloy rad that will fit a 2wd car with a Ford 4x4 i/c without having to hack the rad about some way?
I don't see what the extra rails are for on the top of the Radtec rad?
Neuther the Pro-Alloy one or the Radtec one are exact copies of the Ford one - the depth of the core isn't the problem - it's the extra height at the top.
