XS650 dual piston brake caliper options

[Bryantreams]

Hello everyone, I'm building a 1975 XS650 to road race next season in AHRMA's novice production heavyweight class. I have a set of 35mm forks Gary so graciously sold me. Planning on guessing the internals on them.

I was about to order the pandemonium brake kit to run the Brembo 4 piston caliper, until my friend told me to reread the rule book which states you're only allowed to run a 2 piston caliper.

My question is, what are the best 2 piston calipers that will bolt on? Or should I plan on making a custom bracket for a nice 2 piston caliper?

Also here's a picture of what I'm starting with. Wish me luck! Haha

Thanks guys.

There is a 77 set of XS750 calipers to rebuild. Easy bolt on if strong enough for you.
Need, 5mm rotors

Thanks. I was hoping to find a two piston caliper that would bolt on. If I can't find any that will work I may go with one of these with a nice rotor and pads.
