Well AB, I did the Katzkin install this weekend. What a PITA. Those clips instead of the hog rings look so easy right? They might be, but they are still a major pain in the rear. They don't clip in as easy as YouTube would have you believe. My hands and fingers cramped up 3 times. I went to the school of hard knocks on this one, but learned a lot about what not to do, and some tips that I figured out ( towards the end of course).
First, and foremost, forget any notion you had of trying to keep the original coverings. I started off trying to remove the original covers by keeping them intact in case I ever needed them, I did the back 60 this way, and holly hell was that a nightmare. I just cut the rest of them with a razor and it made a 1000% difference. Second, leave the leather in the sun until you are ready to use. Third, there are some videos out there that have you leave the seat together, I found disassembling them into upper and lowers makes it easier. And my last tip that I learned way too late in the process is to find something to use in place of your fingers for pushing the clips in. Obviously, find something blunt so you won't damage the leather. I used an old iron pry bar, it made a dramatic difference in ease of installation. And along those same lines, find something hard to support the underneath of the foam when inserting into the clips, I used a large rubber mallet. If I had the pry bar and mallet from the beginning it would have easily cut my time in half. On the headrests, they might have a plastic bag on the inside of the originals, keep those bags, they make it much easier to install the foam (they make is slick). Total time taken, 19 beers. On a scale of 1-10 in terms of knowledge difficulty, I'll give it a 6, watch the videos and you'll be good,(just be sure not to leave the airbag cable in the back before you button it up, I'll blame that one on the beer). In terms of physically, I'll give it an 8.5, this install flat wore my fingers and hands out, was much harder than I imagined, the hand cramps were brutal, didn't help that it had to be 100 degrees in my shop this weekend. If you're going to do it, leave yourself a free weekend. Tools needed, cordless impact drill, 13 mm, 18mm, 15mm, T50, T30, T15, T25, upholstery trim tools, razor blades, needle nose pliers to pull zippers, and if you so choose the two tools discussed earlier and pictured here.
