Ok, so I bought a knockoff set of the 4-point docking hardware on eBay. I know, I know.....but for $25 I figured why not? Well, the backrest which IS an authentic HD product doesn't wanna fit on it....like it will but I have to really shove it on and the clamps are kinda chewing up the rubber bushings because it's almost as if the spacers are too wide. So my question is, how easy/hard is it supposed to be to mount or release your backrest from the 4-point docking hardware? I was expecting it to just slip on there and the clamps click into place but that's far from acuality. Could it just be that the cheap knockoffs aren't really worth a crap? I mean, I can get the backrest on, but it's almost as if once it's on, I don't even wanna remove it because of how much of a pain it is to put back on....I like to ride without the backrest but like to take my kids every now and then so I would like to be able to mount or dismount it quickly and easily.
