60 C10 manual gearbox dual brake circuit conversion

[yeah_yeah_na]

Hi, I have purchased a T5 gearbox to do a 5 speed conversion on my 235 powered '60 c10. I was thinking I might do a duel circuit brake conversion (maybe boosted) on it at the same time. I've taken a look through the FAQ but can't seem to see any manual dual circuit conversions, can someone point me in the right direction please? Wanting to know what combo of clutch/brake master cylinder to use for the job with the available space.

Thanks for any help.
