Factory PBR calipers from a Mustang Cobra would fit relatively easy, but you have to watch for the offset. They stick out quite a bit further than the calipers you have. If I had to guess, maybe 3/4" ? They may hit your wheels, then you are going to have to buy another set of front wheels to clear them.
This is what you need. It is a direct bolt-on. There are a few different variations on the calipers. The ones I had were red powder coated with COBRA stamped on the calipers.
