If the radiator's already set up for it, I'd hook them up there - especially if it's a temp thing. If it's longer term, I'd go with an aftermarket setup. Most come with all you'll need to hook them up. I'd consider mounting the cooler down low and off to the side underneath the car, so the hot air coming off of it doesn't pass back over the radiator making the rad work harder. And up there in Nova Scotia if you end up leaving the aod in, I'd plumb it out from the tranny to the auxillary cooler then to the radiator then to the tranny. That way in the winter, if the auxillary cooler works a little too well, the radiator cooler will put some heat BACK IN the fluid. You can use copper line or braided stainless, but if you're careful with the routing and covering of the kit's rubber lines, they'll work just fine. I've been adding auxillary oil coolers for decades to my cars - always used the high temp/pressure rubber lines that came with the kit. Never had a problem. One of them lasted for a good 8 years on my SCCA racer.
