Right, we have done over 5,000 Mopar radios over the years , but we mainly only do A ,B & E body with Mopar .
We don't do any Lil red express, Magnum, Volare Road Runner ,Aspen R/T etc. nothing newer than 1974.
We do most 1960-1976 GM, and Fords as well. With GM we cut it off with the 1976 Corvette and '77 Trans Ams usually.
I have hundreds and hundreds of parts radios around here but only A B E and some C body .Nothing newer.
You might try S & M electrotech in Minn.
Their website is turnswitch.com .
They do a lot of stuff we don't fool with anymore.
