I was able to raise both front bucket seats by doing the following: I removed the outer side covers from both seats and removed the three nuts holding down three corners of each seat. The fron two nuts have a plastic cap which is easily removed with a screwdriver. Each of these nuts beneath are 15mm with a progressive 3/8 USS Coarse thread (starts as 3/8 and progresses to 7/16’s). The fourth corner attachment is covered with a plastic plate held on with a Phillips screw. Beneath that there is a 12mm threaded Torx bolt. First remove the screw and plastic plate. Then, to removed this bolt on the inside rear of both front seats you will need a type 45 Torx socket. (Note, these seem to be torked down very tight. I actually stripped one and had to use a Dremmel to cut each side and then used the claw of a hammer against it while hammering the head with another hammer to turn the stripped head and remove it).

After both seats were removed, I placed a 7/16 – 1 ¾” coarse threaded coupling nut (5/8” O.D.) on the three studs protruding from the floor for each seat. To that I added a 1 ½” cut piece of 7/16 coarse threaded rod. For the two inside rear corners, I purchased two 2 ½ inch 12mm threaded bolts with 11/16” heads. Before placing each seat on the three new 7/16” threads, in the rear corners, I placed three 5/8” nuts (placed one on top of another) as a sort of spacer acting as a 1 ¾” washer (actual thickness will vary by manufacturer). Finally, before placing the seat back on, I covered the hardware with 1 ¾” black vinyl tubing to hide the shine from the new hardware. Then I placed each seat back on sitting perfectly level, now only 1 ¾” higher!

For each seat, to each of the three studded corners (now with coupling nuts and a 7/16’s threaded extension, I placed a large 1” OD washer over each hole, followed by a nylon 7/16’s locking nut. To the fourth inside corner of each seat, I first placed the same washer, and then the 2 ½ inch 12mm threaded bolt with 11/16” head. Then I replaced the fourth inner corner plastic plate with the Phillips screw from where they originally came. Job complete! I can see!
