Better brakes for my 58 panel...

[qksilver]

I have a 58 panel that i paid way to much for and want to make it road worthy. It runs and steers well but the brakes................
What can i do to get it to stop straight and fairly well?
The first thing I know is to install a dual M/C and replumb the brake lines.
who, where can i get modern high performance brake shoes, spring kits, M/C and mounting bracket, and proportioning valve?
M/C Bracket used?
what used proportioning valve
I want to keep my aftermarket wheels so i was going to stick to the drums
Unless anybody has a cheap way to do a disc brake swap keeping the wheels and using roller wheel bearings.
Thanks,
Steve
