Shawna G Northridge , CA February 22, 2016 Appliance: Model 12-6663-30 1957 oven hinge replacement With help from my Handyman Randy, it was a cinch, taking only 15 minutes tops! With assistance from Shawn the fantastic Customer Service agent, we were able to figure out the parts from the almost non-exsistant serial number off my late 50's O'Keef & Merrit in wall Oven. The parts were correct and it was fixed in a flash! Thank You AppliancePartsPros.com, I will recommend to anyone needing a hard to find part!
