I have two sets available, a Gen4 and a Gen5 available. Retrax Pro MX for 2019-up Ram shorted, NOT Rambox. Canister: 61822, standard rails (not T-rail): 82245 (update: T-rails also available) I had it installed on my 18 MegaCab with a LOT of washers and longer bolts in place of the nylons to make up for the width difference and I just bought the right size. Missing parts: nylon clamp screws (bolts work fine), keys. I might have another lock/key available I can help install, depending on when. Best offer but don't lowball me, this is a $2k setup. Both work great, I just went with a shell instead.
