67/68/69 cuda dilemma

Looks good Matt. Last few cars I've done, I mount a stacked plate cooler just about like the one above, and mount it solid like you did. Then I buy 2 bulkhead fittings to mount to the radiator support, and run hard lines from the cooler to them, and then from the engine compartment side....down the frame rail behind the steering box, and stop them on the frame rail even with the fittings on the transmission. Then I get some steel braided lines made to go over from the hard lines to the transmission fittings. The braided lines provide the needed flex, heat protection from exhaust, and they are up against the floor pan out of the way. You also don't have to wrestle with them if you need to replace a starter. Kind of a simplified explanation, but it works slicker'n cat poop on linoleum! I'm gonna do the lines on my 65 Barracuda project that way.
