I need to pull the transmission tunnel floor pans (and modify them) in my '71 to prep for the 4spd swap. However, a previous owner bed lined the inside of the Jeep right over all the seams and bolts for the floor pieces. Does anyone have any advice for removing the bed liner where I need to? I'd like to leave a clean edge around the floor opening if possible. I was going to try a heat gun and a scraper.
