Hi, Nice guy in Vancouver B.C. suggested I reach out to you (works at Marathon, of course I don't remember his name). 
I have a broken kitchen cabinet hinge I'm trying to fine a replacement for. All I can tell you is that the brand is DTC. It is stamped with Z90 with a 2 underneath side. The roundish insert side has D48 stamped on the underside. THe hinge swivel part has a faint stamp that appears to say 4CLA over the numerals 02. 
Any chance you can decipher this and sell me a replacement? Hey, worth a shot eh?
Thanks,
Bob Leahey
