Just incase anyone is thinking of doing a shark fin conversion on a 2018 and ? year RC truck, it seems like the front mount sloped roof angle on a RC might be different than the rear mount angle on a 4dr truck. I just finished mine on my RC and needed an antenna base, a cable that ran the roof header / right A pillar and a cable that ran inside the dash to the radio.
I needed to change the cable all the way to the radio because my factory setup only had the 1 mustard color connector and I need the 2 connectors to run everything correctly.
