Brake and sway bar upgrade questions

[64C10Fleet]

I know some of you have already learned lessons from doing this stuff the hard way, so I'm hoping to learn from you this time around. Truck is a '64 LWB and currently has an all stock suspension and brake setup with the exception of a dual reservoir master cylinder upgrade.

Plan is to do a disc conversion on the front and install front and rear sway bars. The more I think about it, I'm not sure the rear sway bar will make that much of a difference. I'd like to keep the stock ride height, suspension components, and 15" wheels I have currently. The engine doesn't make enough vacuum with the cam that is installed, so I won't be upgrading to power brakes.

I appreciate any help. I'm willing to buy a complete kit or piece something together.
