Thanks Mark, will chew your ear off at Pod early Sept with Jonny, a few beers and some boogying to Miss PerryMoffy boy, got a few cars with diff coolers fitted.
We can supply the parts , think I have a few S/H Hitachi oil pumps in stock , need to be careful where you mount the cooler to get a good air flow and not be easily damaged by kerbs or debris and the pump needs to be switched on thermostatically (sp) diff oil is too thick to pump when cold.
Give me a ring if you to discuss more.
Mark
