Custom Installation On an old School Bus

[GMBusLife]

Hey y'all, I've got a little bit of a problem here. I work at a salvage yard in NC and ended up getting a 15882767 radio from a car before it went to get crushed. I have an old Thomas Built bus that I've been working on and trying to make into a custom camper for trip with the misses. I wanted to install this Radio but, no matter where I've gone and who I've spoken with, there doesn't seem to be anyone able to help me figure out where to get a harness for this thing and what steps I'll need to take to wire it in. I'm really savvy when it comes to this stuff usually, but this one has be scratching my head.

 

Any help in figuring out what I need to do would be greatly appreciated!

Sounds like it would have to be a custom made harness and you'd probably have to make it.
