I can tell you that all the radios from that era used the same 3 plug harness. Blue, White and Black. So it will plug in. The CB option requires a tri band power antenna and the SW adjusted for CB reception. If that doesn't interest you to have CB function, then assuming the radio is functional, it will be a plug and play job. As you are aware, that radio comes out from the back of the dash. Rather time consuming with rear brackets and clearance issues. Make sure to clean the tape head and capstan with achohol and a cotton Q tip. Haven't listened to Tom Jones on 8 track in years!!

Wow, that Cadillac mic is really sweet, i need to get one of those for my cobra CB...

You need to be very careful about the CB radio. DO NOT use it if you have not set the SWR (standing wave reception). If the SWR is wrong the radio can explode/catch fire. Do some searches on Google and you will find all the information you need.
