Ok, I said I'd do a write up on this, and have finally taken the time to do it. Materials that I used. 5' of 1/4"x1" flat bar. 4ea- 2"x3/8" bolts with nut, flat, and lock washers rubber bushing material about 1/2" thick to slide over 3/8" bolt for cushion. 4ea-1/4" thick x 3/8" flat washers 8ea-3/8"-1-1/2" bolts with nut, flat, and lock washers 4ea-7/16"x1" bolts with flat washers I first made a bracket to relocate the mounting bolts from the oringinal postion of 13-1/2" to accomadate the new wider tracks holes of 16-1/2". I started with an 18" length of the 1" flatbar. I found the center point of that piece at 9" and measured out from that point to either side 6-3/4" to give me a distanec of 13-1/2" O.C. I then drilled the two holes to 3/8". I then measured from the center of one hole out 1-5/8" (O.C. to O.C.) to postion one of the 2"x3/8" bolts to be welded to. I did the same for the other side but measured only 1-3/8". See picture below. This is what it should look like. I found it easier to remove the track assymbly from the seat to mock up the rest. Use the 4 ea. 7/16" bolts and washer to secure the new piece you made to the front seat original mounting holes. Bofore doing so, place two of the 1/4" thick washers under that bracket (one per hole) so that you have no gaps between the flat bar and the floor pan. Do the same for the other side. When mounting it, the side with the bolt that's 1-5/8" away from the hole you drilled goes to the drive shaft tunnelside. Place your rubber bushing material on the "new" studs. The whole reason eveything is so thick is because the new electric motors have to clear a hump in the floor pan. You can see it in the background of this picture. Mount your new tracks to the new bracket you made. The rear brackets are all the same. Cut 4 pieces of 1" flat bar to 2-3/4" long. 4 more to 1-1/2" long. I don't have an angle finder so I don't know what it is. You can see from the picture roughly what it is. It's best to tack it and them bend it to the exact angle before final welding is done. In these photos, you can see how I attached them. I drilled a 1/2" hole (wiggle room) towards the rear most part of the longer tab so as the bolt that bolts to the track frame doesn't interfere. Once that hole was drilled, i mocked up the rear brackets and marked the floor pan where I was to drill a hole so I could mount these angle brackets to the floor. At the same time I marked the hole to be drilled on the undrilled tab on the angle bracket. If this sounds like jiberish, it's because it's hard to describe this in writing. Reference the pics and you should understand what I'm talking about. Mount these new brackets with the remaining hardware. These seats sit a little higher than stockers. Keep this in mind if you're over 6' tall. I'm 6' and fit fine, but any taller and your going to need a sun roof or T-top. Hope this helps anyone thats thinking of going this. I scored this full set of seats for $400 bucks, so I was deadset on using them. Next post is the rear seats.
