If you are looking to keep it stock original then I agree with Dan, it will be better to get some made from a source like he suggests. Otherwise if you are not necessarily looking for originality, then ask around at your local upholstery shops. We've discussed this before and apparently there is a HUGE variance in prices; some regions of the country are really expensive while others are not, and some local shops will be much higher than others. In my area I can get a nice complete reupholstery job on two seats for about $300 (material and labor). Compared to the prices for most covers it is less for me to drop the seats off at a shop. You are in Texas so depending which part, you might find some really good upholstery shops locally. I know where I am there is a very large population from Mexico and that includes some extremely talented craftsmen in several specialities - including upholstery. That's why I can get seats done at a reasonable cost. Being close to Mexico you may find the same there?
