i was scoping out the radiator in my 89 dodge. it has the same style mounting bracket as the sweptlines, and is even a top and bottom tank, not a cross-flow. but its a 2 core all aluminum model, with plastic tanks. the best part is its still available at auto zone and numerous other places. i don't have any measurements to compare to as a reference. the truck i have here doesn't have the core support in it any more. by the eyeball check it looks as though this newer model would practically bolt in. best part is, it has kept this 69 model 318 2bbl running at 185 degrees in the 105 degree NM heat. she creeps up close to 200 at a long light, but the second you start moving it runs right back down to 185. if someone can get me some measurements, side to side and top to bottom of the mounting holes i will compare it to whats here and see if this might work. might be a simple and easy solution to the on going question about where to get a radiator for these trucks.
