I was looking at how Mach4 retrofited the oil cooler lines to beefier, aircraft style hoses....it looks very interesting. I've also looked at stacked plate fluid coolers. The only issue I can see is the inlet/outlet would come out right where the windshield washer fluid bottle sits.....might be a problem although I can't say for sure....

My concern on this car is I don't know the age of the oil cooler lines....they are at least 25 years old which to me says time to replace.
