I was wondering how hard it is to replace the rear window seals on the ?94-?99 Discovery. I got an estimate for $200 for the labor to replace the rear door glass seal, and the two rear quarter window seals, but the parts were not included in that estimate. I?ve found the seals online, and they are not terribly expensive, but I was wondering if they could easily be replaced by a do-it-yourselfer? I would think the rear window would be difficult just because of its size and weight? Thanks in advance?
