 New to the option list at PRP are these adjustable-height headrests. |  Also new to the option list is an inflatable lumbar support stitched into the lower back of these Daily Drivers. Shown is the pump with the deflator button to release the air. |  The slider brackets come unassembled and needed to be bolted together with the provided carriage bolts, pointed up as shown. We had to slide the mechanism forward to be able to get in the rear carriage bolts, and back to attach the front carriage bolts. |
 We secured the suspension seat to the slider using our Grade 8 hardware. To use a washer on the inside, we would have had to grind one side flat to clear the bracket, but the Nylok nut alone should provide enough support. We also routed the lumbar line in between to keep it located where we can reach it once everything's installed. |  As a starting point, we selected square tubing with the ends cut at 45 degrees welded to tabs with a hole on each end to be able to use the stock bolts. This will allow the mount to stay low, as the tubing is only as high as the hump. |  Once we determined the rail length required, we drilled out the four 3/8-inch holes in the slider stud mount rails that will tie in the front and rear stock seat hole supports. |
 The rear support was fairly straightforward to fabricate using square tubing with hole tabs that also use the stock bolts. On our 4Runner, the rear passenger-side and driver-side bolt hole alignments were different. Once the rear mount was bolted down, we set our mount rails to our desired seat slider location and tilt. |  After tack welding the slider rails to the mounts, we installed the seat to make sure the angle of the seat, and slider operation, was within our parameters. |  Once we had checked the fitment of the seat, we removed the mount bracket and welded up everything. We took special care to make sure the rails were able to mate with the bottom of the slider - this is the key to smooth operation of the sliding mechanism. |
 This is the raw bracket after the welding process was complete. Notice the gap on the underside rear of the rail to leave enough space for the washer and Nylok nut that will secure the seat and slider. |  Before snapping this photo, we took the time to primer and paint our finished bracket to keep the rust away. As mentioned before, notice the staggered tab holes on the back of this passenger-side bracket. The driver-side is different and looks about even. |  Using the supplied connecting rod, we slipped one end through a hole on the non-lever side and folded it over about 1/4 inch. Then we stretched it across to the lever end hole, bent it at the correct length, slipped it through, and folded it over. |
 Bolting the seat/slider combo to the custom mount as shown, then installing all together, is much easier than trying to install the mount only into the vehicle first and then trying to get the washers and Nyloks on without much room. |  Lastly, we attached the two stock front bolts and then slid the seat forward to attach the two stock rear bolts. |  |
