does anyone have the measurment from mounting stud to mounting stud,for a 26" rad support and a 22" rad support. I'm not sure what rad to order, my measurment from stud to stud 25". I'm assuming a 22". The current rad is about 18-19" and has big tab brackets on each side.Since the current rad (copper/brass) was just about enough for my application I assume a 22" aluminium rad would be much better.I really don't want to mess around with the support, I just want something that will mount in the factory location.Thanks in advance.
