There are some extremly good after market Kits that are made by a company called Rostra and these are excellant and will probably cost no more than $100.00 -$150.00 installed professionally.
We sell these a lot to new car dealers and really never have any problems.
Go to places like American Sunroof company or any reputable aftermarket leather seat supplier in your area and ask them.
