Just got a backrest for the LT. It's exactly the same frame as a Backup,the ones you always see..You know the arched frame with 2 holes in flat tabs that are at an angle.My Question is. Where do you bolt it up to? The front tabs of passenger seat,or the back of the drivers seat? No factory holes or bolts line up.Do you drill holes.Not sure.Help would be grateful... Update. Well. You all were right. it sure don't look like it will line up but i removed passenger seat front bolts.I thought..MAN ..These holes are way off,no way do these go there!!.But i threaded in one bolt on one side in loose.Then kinda pressed on backrest frame and forced the other hole to line up.It's a close fit latching the front seat closed too.But i got it. Thanks to all who chimed in.
