mustang interior change
 

I have a 99 v6 and I have the beige interior and I would like to swap to the black interior anyone have these parts kicking around or no were I can get them

Local wrecking yard would be the place to start, second option would be to remove the panels and paint them with vinyl dye.

+1 on what Pony said. Be suprised what you will find at your local wrecking yards.

X 3. Wrecking yard is a good bet. Latemodel Restoration is also a good resource. The dye mentioned by AP is also quite good.

I'll have to go to pick a part in chilliwak Ralph's likes to give random prices for there stuff.. Is the dye hard to do or more like a spray on?

The vinyl dye is already in a spray bomb, just use it like regular spray paint, nothing special about the application, you're just spraying vinyl dye instead of paint. Acts the same way as paint when you spray it, shoot too much in one spot and it runs, and you gotta let it sit after it's sprayed to set up and dry.
