You're going to love the WKOR's...excellent fit & finish and easy to install. I replaced my cats recently and checked the threads in the frame for the mount behind them (which were clean fortunately on mine)....that would be the only bastard issue if the threads need to be chased. The bolt that everyone cranks about on the brake line really isn't that big of a pain if you take your time.
Got out in northern Georgia and hit up Earls Ford Road. If you haven't been on it, it's a nice out and back trail that runs down to the Chattooga River and fords warwoman creek. Pretty neat trail. If you're ever in that area, do yourself a favor and check it out.
Land Cruiser 80 power seats gear caps experience a lot of axial load when you bottom out the seats travel. Overtime they will eventually strip and work themselves out. This will lead to the inside gears getting misaligned and a complete failure of the seat fore and aft movement shortly after...
