I just installed Ridies (I think,
@cruisermatt correct me if I'm wrong) leather covers on my daughter's OEM leather seats.
Other than being a royal PITA to install, I have one observation:
» these were made for OEM cloth seats, not OEM leather seats. The outside bolster piece isn't long enough and there is no access hole for the power seat control switch assembly. All that makes the installation much harder than it should be (no reflection on the supplier, just a data point for consideration).
I used zip ties instead of hog rings, and I'm glad I did. Aside from preventing me from acquiring another tool, which I would never use again, this made adjusting them, which was inevitable, much easier than it otherwise would have been. It took all but one of the 100-ct package.
I tried to get Land Cruiser Heaven to supply covers, but they tried their best to make sure I didn't want to do business with them; they succeeded.
I have no long term use update, because they've only been in for a week, but they look acceptable, given the fact that they were installed by a completely unprofessional upholsterer. I thought the wrinkles were bad, but she didn't mind at all, and now, looking at their ad copy, apparently that's what they intended.
