I picked up a set of chrome 17 inch split 5-spoke wheels at a swap meet. They came with chromed plated center caps with the running horse logo. They look like the factory stock 17 inch wheels found on the 96-98 GT, but I have only seen those wheels with a brushed or polished finish. I have seen the 16 inch GT wheels and 99 17 inch wheels in chrome, but never the 96-98. Was a chrome finish a special factory option or do I have a cuztomized wheel?
