Same carpet used on Chevelle, GTO, etc. Even if yours has floor shift, get carpet for COLUMN shift. I've heard too many complaints about the press mold not being close enough for the floor hump. Also, add more under carpet thermal/ accoustic insulation. I have found that getting two 4 ft by 6 ft rolls is enough for one car floor. I used the replacement 'tar paper' for a rough pattern. What color is your interior carpet, and we MAY be able to get you in line with the correct color. Personally, I recommend ACC carpets...
