Charlie M. I went back through your posts trying to figure out what kind of car you needed a radiator for before just bailing off into a recommendation. I finally understand where you are coming from and, with great empathy, can say "that truly sucks!"
As an option to you and/or others, Griffin Radiator has the the specs for the Sabre radiator on file. From memory it is a 12"X24", 3 core, upper right 1½" inlet and adjacent 3/8" bleeder tube, lower left 1½" outlet. Prices vary over the years and, believe it or not, mine was cheaper than the ones sold to Sabre. (Go figure!) I have the mechanical drawings here somewhere if someone wants verification of my CRS handicapped memories, or just get in touch with Griffin. I don't think one can buy a better radiator than they make.
