I am trying to compare the Am-Std Titan Pro Right Height Elongated Toilet # 2839.016.020 to the same or similar Eljer 091-077 toilet. When I call Eljer customer service, I get American Standard. Customer service twice told me they were identical toilets, yet I get the distinct impression they really don't know. I haven't been able to locate spec sheets for the Eljer Titan that show the measurements and diminsions for comparison. I have the specs for Am-Std. Does anyone know if these are IDENTICAL toilets? Or are there minor differences? Was also told that the only places to buy Eljer in Texas was Ace and True Value Hardware. Thanks from Texas.
