SOLVED!!!
Apparently someone put a 91 suburban passenger fender on the donor truck I removed it from. 😡 it took awhile to get ahold of a stock antenna assembly as these parts/trucks aren’t Readily available anymore
I installed the mounting base, ran the cable, and ditched the windshield antenna cable
I even installed a cute little antenna to show it off. I’m happy I didn’t waste the time and work to cover it up.I guess in the end it helps to be patient and persistent
