Had the part for an old sears opener that broke. Fit perfectly. Bought an extra one for next time. The one problem was waiting for USPS to deliver. Thanks for the quick response and would buy from again.
A slight different design as far as where the terminals are located for the power to connect but other than that I popped the old socket out and inserted the new light socket. My garage door opener is a Craftsman purchased in 1998.
