Here's a good
third seat how-to link. The how-to is a good guide. During my install I realized one difference to keep in mind. The member that made the how-to used a passenger seat whereas I used a driver side rear seat. The front legs of the driver/passenger side seats are opposite of one another so if you use a DS seat the mounting of the front legs as described in Step #9 of the how-to is not correct. Instead of shimming the front legs I used a BFH to
massage the floor flat. To get the legs lined up Ryan and I used a chalk line.
Here's a bunch of pics I compiled from over the years. I can post the links for the threads these pics came from but there's not much if any tech information in them. I really enjoy the aesthetics and functionality of this mod.
