you wont find it on an ma61...trust me i have two empty engine bays 1m apart..they are very different, holes cut in front panels is the only way on a 61...as i said i have to make 2 in mine (one for each extractor)!
You are lucky enough on an ma70 to have space next to oil cooler lines and shit that runs from the front of the car to the engine. I actually found some 90mm pipe in the shed, so i spose ill have to settle for it
I'll get pics of it finished before too long...Am doing it before she goes back on the road.
If you're wanting a good mod for ma61 cooling, come over and ill show you what i made for the front a/c fan..you can manage to fit a 12" flat body in there no problems! Just gotta weld a bracket...Im also cutting vents in my bonnet similar to a 69 e-type jag.
