Trans cooler lines to Rad

Yes, that part I have covered as far as inverted flare and such, I believe they are 5/16.

I guess my question is do you guys make your own, or did you buy pre made? If you bought pre made, which kit?

I am running a 360 with 727, champion rad with factory cooling line fittings/positions


Any of the aftermarket/reop line kits will be copies of the oem lines. If the kit you got was correct for your car, of course it won't work with a aftermarket radiator and headers. That's why I suggested you make your own.
