MY '70 desperately needs the fabric and foam on all of its seats to be replaced, it is rotten and there is a big hole in the drivers seat and you can see right through to the springs. How do I go about getting permanent replacements? I don't particularly want to just use seat covers, it really wont look right. Is there a type of shop that specializes in re-upholstering car seats? Or will other years (such as 79, theres a 79 near me in a junkyard with good seats) fit my Caddy? I do have power seats on both passenger and driver sides, would the rear bench seats also fit?
