It was easy installing, but the button head bolts pulled thru the threads. The bolts are obviously short, but they are tapered?? That means only maybe 1/8" of threads are holding the backrest?? I had to take it back apart and adjust the bolts to the correct position, then welded the bolts in place. Seems fine now

Driver seat back rest
The installation video and the instructions were not quite accurate. Had to improvise a bit.
The back rest position doesn't seem to stay in place. Constantly have to keep adjusting the position.

Great Backrest
This backrest is comfortable and adjustable. It also has a small storage pouch for the passenger. I like that it matches the seats on our ‘24 RT Limited. The bracket wasn’t very easy to get into place, but it went and it’s secure. Also, the bracket bolt is too short. I had to use only the flat washer, as the bolt was too short to use the lock washer. When adjusting, the seat kept slipping all the way back, no matter how much I tightened it. I finally just turned the adjusting plate around, so that the seat is all the way forward. This is comfortable for me, but might not be for everyone. Overall, I like the backrest.

Excellent Backrest
The product arrived in good condition and on time. It is installed on my Spyder and working well.
I had to thread one of the holes. It did not have any threads other than that perfect fit.

Quality product, easy installation
This backrest meets all my expectations. It is made of good, strong materials and matches my seat finish exactly. The backrest hits my back at the perfect position and gives excellent support. The installation instructions were clear and easy to follow. The installation was very quick and easy. My one complaint is that the screw that holds the fender washer should be longer. We could not make it go in with the lock washer, so we used loctite instead of the lock washer.
