climate control bulbs and sockets

[fruitcakesa]

I dug into my center console and managed to get the unit out with some sweating and swearing. PO had installed a Pioneer Radio which was marginal and the wiring was kind of cobbed.
The bulb socket that fits into the rotary temp control was gone and the bulb was wedged into the contacts but it was pulled from the back of the control. This is on my w123 dash panel
Is there a source for the individual fittings; or do i have to get a piece of harness. Anybody have something in their parts bin?
