What late model booster m/c fits a 1st gen Camaro?

[69MyWay]

Hey guys, for my 69 Camaro with C5 front brakes and 2001 F body rear brakes, I need to know what late model Master Cylinder and Brake booster is the most direct fit to the stock 69 pedal....AND,

What else is needed to connect it?

If you guys remember, I hid a non-power master cylinder in the side cowl of my 69 to have the ultra flush firewall.

Well...I am going to be driving the car a lot more in the future as a daily driver situation and need more brake assist.

PLEASE - part numbers, fitting issues...etc, would be Very helpful.
