Thanks guys!
I don't know when these brakes goes on the car, so I am basically looking for a used set due for a refresh. I've had a plan for a big brake upgrade for years and collected most of the parts, but the status on these cars has changed now being a young classic which dictates the market value. Based on that it should be kept original. But my car does already have major upgrades with the supercharging (w/decompression i.e. turned down pistons) and color change from 172 to 040. And it is after all my car and my preferences put in it, and bolted items can easily be reversed. Time will show, but I have to collect the stock items missing on it when they're still around.
