I need recommendations from anyone who has purchased an aftermarket radiator that has fit in their 73-91 suburban using the OEM mounts. When I go to auto parts stores/websites, they seem to have 15 different options that are all "gauranteed" to fit. They mostly seem to revolve around either a 17" high core, or a 19" core. I have a 19" core, but I ordered one of these and it didn't fit, it was like 1/4 inch too tall and the OEM rubber pads and mounting clamps didn't fit to hold it in place. I've worked and worked using the specs that are listed for vairous alternatives and they all seem to have similar specs and I don't want to go through the hassle (and shipping expense) of trial and error shopping. Can anyone suggest a radiator that was truely a bolt-in fit?? Thanks!!
