Oregon ssp Motorola Module, phone/radio?

[ssp91ssp]

Now that we know it was a phone setup , looks like that's the only thing my car was fitted with .
Check out the pic of the mounting holes...After all these years and you can still see the black line they drew on the console as they mounted the bracket.

If any site member has a car phone of that era ??? please let me know and how much?? Thanks.
