Got this idea from another site but it works well. I simply made spacers (7 total) from 1" X 1/4" bar stock 3' long ($8.00) from Lowes. You install the spacers under the seat brackets so the bottoms lift up in the front and the backs tilt back just a little. It really doesn't look like much, but the difference is very noticeable. If you have spent any time in the back you would know the seats sit too straight up to be comfortable on longer trips.
18mm socket and breaker bar
These suckers are in there tight. Did I say : These bolts are in there tight. You will need a breaker bar and some serious muscle to get these out.
Unbolt the 4 feet and move the bottoms up with bungee cords to keep them out of the way. I took my rear doors off to get in and out better also.
The next part was hard to understand without looking at the seats and the brackets underneath. You need to take out the 3 bolts on the bottom section of the L brackets that hold the upright portion of the seat. The bottoms of the L brackets will move the seats back just a little but it really makes a difference. I loosened the 3 bolts on the top of the L bracket to make sliding the stock under them easier. Cut the stock 2 1/2" long, drilled holes for the bolts, painted them, and installed them. The bolts are more than long enough to do this without worry but if your concerned don't do it.
Next cut 4 pieces 2 1/2" long, drilled holes for the bolts, painted them to prevent rust, and installed them under the four feet in the front. (Pictured)This lifts the bottoms so they support your legs better. You don't have to do this part but it does help and you have to take out the bolts to get to the bolts for the back anyway. I left this one a little long so you could see it under the foot. -Maybe is was just longer than the rest - you decide.
All done and it does feel better for the rear passengers. Of course this doesn't do me any good. Was this worth all the work? ....
Yes, if you ask someone that sits in the back most of the time!
