Back seat elimination

for a non racer deal, 1967 cuda's deal is the way to go. like you say, dealing with the wheel tubes will be the biggest challenge. since you don't have molded carpet for this a rea, seems like the way to attempt this is cutting slots in the carpet so it will mold and bend.\ I would pick up some carpet remnents and just work ay it. 3M SUPER adhesive works good.
