defrost indicator lamp for SC

[SCWDP911]

I am looking at purchasing this from another board member:

Black plastic defrost light box w/bulb that sits on floor between front seats by heater/choke levers, p/n 914.632.107.00

I just want to make sure this will fit my 83 OK. I looked in my Bentley and could not find the right info.

Thanks,
Shane
