I just had the valves installed on my bx2350. The plate to which the couplings are attached mounts on the right side of the ROPS and the levers for the come up through the available slot in the right rear fender. I can take a photo and send it to you but I don't know how to attach a photo here.
I have the BX7326 Valve kit which allows me to operate the chute deflector and the chute rotation.
Unfortunately, the BX7326 Valve Kit doesn't fit the TLBs (22, 23, 24). Subframe interference at valve mounting point. Folding ROPs and rotating seat interfere with QD coupler mounting bracket. This is not to say the kit can't be modified to work...don't know...but it's not plug-n-play. There are a lot of us with TLBs that want it to work, but so far no one has done the mods (and told us about it). If I could stop using mine long enough, and lived close enough to a line/hose fabricator...I'd give it a try.
