Hello All,
You can add the park brake to 2019, and possibly older machines. Depending on the brake pedal, you replace the pedal or add several parts (lever, clip,bushing ,spring) and install. I just did mine for the cost of $32. I found the link on Facebook, Defender Nation, or Cab Nation. Cant take credit for the mod just passing it along. Admin, i hope listing the other sites is permitted. I could also list the parts needed if necessary. The other site just has such a good write up on it i dont think i could improve on it.
