That’s what I’m saying, you should’ve seen some of the gaps I revealed on both Doby and Booger when I removed their original seam sealers. Of course they’re fox bodies, the classics may have had slightly tighter tolerances.Are you talking about just filling the gap by the wheelhouses with seam sealer? If that's a fine way to go, I'm down with that.
Aftermarket parts are notorious for not fitting just right. If it’s not a structural issue, improvise.
