Bringing back a 510 GT4

[the head]

Hey all,
I am working on a tube frame old 510 race car, working through parts sourcing and trying to find out more about it's history, I am having a bit of trouble finding a vented disc to fit it's MK63 vented rotor calipers. My next big projects are overhauling the suspension (currently working to source new coilovers) with a goal of having it's first SVRA race be The Weathertech Challenge (Formerly The Hawk) up at RA in July. There may end up being a lot of dumb questions as I have very little documentation besides a typed up story of the car from the original builder and some copies of parts catalogs so please bear with me on some of the parts sourcing questions. These are from when I got the car last fall I will update the project to current when I have a bit more time
