SA vs. FB rad mounting
 

just got an SA rad to replace(for now) my leaky rx4 rad, thanx rotarycrazy. without removing anything from the car, outside of the fans to see how much changes will be needed for the mounting of the fan, rough measurements show there's a difference between the bolt holes(left to right) on the SA rad compared to the FB support by a good 1/8" or so. i can make it work no prob but just wanting to check with those that know for sure.

same thing, no need to mod it. it will bolt right up. in fact, Im using 79-82 RX-7 radiator in my RX-3s

yeah i figured as much. i can make it work regardless. had to redrill holes in the rx4 rad to make it fit. just trying to get a head start on what's needed to limit down time.
