I just now put one in from napa part#(782-1600) with the green  light ring .
It was to small and pulled through the dash hole but I solved this by using
a rad. fan switch crush washer to back it up with.
Perfect!     looks stock, and now works  with
 "normal "  accessaries.

I cut and replaced connectors but a set of adapter jumpers could be made to
preserve the wiring harness if you desired
