No disrespect to anyone intended, and I hope my blunt comments don't get misinterpreted, but after close to 60 years working on these old rigs, I tend to draw a pretty distinct line between what's actually beneficial, and flights of fantasy. I've run oil, transmission, and even rear axle lube coolers at times, but they've always had a specific purpose, like keeping a race car engine together that's running 250% of its original horsepower, or keeping the gear lube temp down on a sports car rear end that's negotiating 20 high speed turns a lap on a road course. Doing race car stuff on a street vehicle just doesn't make good nonsense, most of the time.
