Hot 998 radiator

[Dr S]

Frustrating day today, carbs in, engine all wired, rad in.

Water p***ing out... Looks like the super 4 core is holed.

The motor is a circa 75bhp 998 cooper engine, which will see some stick occasionally. I see minispares are selling a 3 core radiator for historic racing. Looks like it'll fit into the shroud without me needing to learn any new words?

Anyone tried them? Recommended? As much of a sod to fit as a 4 core?
