I just did this mod. It took me two nights to finish one seat, mainly because the seat zipper broke off!!
I was all finished and trying to zip the seat down, pulled a little too hard and the slider came off the track. I had to take off the zipper stopper at the bottom and try to put the zipper back on the track. Well, I couldn't get the zipper to go on the way it was, so I put in on backwards. It now zips UP to close and down to open. I think it kinda makes it easier honestly.
The plastic sliders that hold the bottom together really are a pain to put back together. I needed someone to help me hold the leather close enough to zip it.
The seats are so much better now. Much more supportive! I love it, I'm probably going to do the passenger side but I have to see if my girlfriend likes it before I do that.
