'67 Barracuda Disk Brake Up Grade

I was wondering if anybody could chime in on my Brake upgrade. I have just aquired a '67 Barracuda. It has the Kelsey Hays SMB Patern power disk brakes. I know things have changed since I did the Valiant alot of companies are offering kits upper control arm's with BJ and control arms already pressed in. What my questions are 1) if i decide to keep the PB will the brake booster and MC work with the new set-up?
2)will a gear box from 73 up duster/dart work with my center link?
Thank

I've included a picture of the aftermarket brake booster/MC.
I do prefer manual Disk, I know I would have to change the
rod for M/C, is that correct.
