Mine is a 2021 model, and I've tried to find something from Branson but unsuccessful. Can you point me to a website?For the recent 20 series Branson has a factory rear remotes kit. It's not made by WR Long. The valves themselves bolt on to the rear transmission housing where the feed to the 3pt is. On the open station there's a linkage to the levers by the seat. The cab model uses cables. The only drawback is the levers have a little slop due to the linkage, and there's no float or detent available.
You can get WR Long 3rd function kits from EverythingAttachments.
