Does anyone know who might sell the factory seats in leather with the 6 way power lumbar I presently have cloth.

Why don't you contact a big auto salvage yard in your area, you should be able to find some good leather seats out of wrecked low mileage Siliverados or Sierras, if they don't have them they can run a search on their locator's, make sure to tell them your only interested in 2004 models.

Does anyone know of a place that sells take offs from conversions???

Most of the time conversion companys start off with a LS trucks so they wont have leather seats to sell.

I answered my own question found a guy on the web....http://www.sonnystruckseats.com/chevy.html

why don't you use an aftermarket leater kit. kazkins makes a great kit. i think the quality of the leater is much better than factory.
