Want to remount lexus front seat
Make sure the pedals don't adjust, first. I'm sure that won't be a perfect fit, but it may buy some time. This isn't an easy task. First, figure out exactly how much room you'll need (don't go over).You'll want to pull your seat, and get it out of the way. Since you know EXACTLY how many inches of extra length you need, simply measure back from each mounting point, and mark it. Get under the car, and measure the same distance back on all 4 points, and mark it, making sure you aren't obstructed. From that point, fabricate your way in. You may be able to simply drill 4 new holes and move the seat, but you're probably more likely to win the lottery. Go into it knowing that you're going to run into all kinds unforeseeable problems. Just accept this fact, and it'll help the process. Adapt and overcome, and repeat.
