Sure. I will also send you some pictures when I get the car back in 2 weeks t=
ime.
What we did was to buy a small 6 row cooler (I think but will check) that w=
e mounted to the boot (trunk) floor by the inner rear valance. We cut a larg=
e hole (8"x 3" or so) in the boot floor just in front of the oil cooler and=
manufactured an air scoop which we attached to the underside of the boot fl=
oor. The cooler pipes were attached to the diff and cooler and driven by an o=
ld Lucas fuel pump.
As I said I will send you photo's and more precise measurements when I get t=
he car back from the workshop.
Hope the above helps for now.
