my 68 cuda engine compartment
Nice plumbing. Love the "all hard lines" result. I installed a similar plate type cooler in my Dart, but a cheaper model with hose nipples, so had to use short sections of rubber hose. I plumbed in a temp switch. It has AN fittings and would have been much cleaner on a threaded cooler like yours. On mine, it was more fittings and rubber hose.
Any time you customize, it takes forever. After much consternation I decided to bypass the radiator cooler. I didn't want to risk coolant in the tranny. My Newport's 727 runs cool on just the after-market cooler, and that is a cheaper tube type.
