46 Interior dome lights help needed.

[LBCD]

good afternoon gang....I have been looking on the web for interior dome light parts and have found a harness that Macs etc has but not with the spring assembly. Is there a wiring harness available with the spring included for the bulb housing?

I have the housing with the switch included but the mechanism is worn out and fallen apart. I will try to fix this but if not a door button seems like a good option.

and since i know diddly squat when it comes to electrical hopefully someone can chime in with some info. thanks
