New to 60-66 Need Suspension/Brake/Steering advice

[jweb]

Just bought a '64 suburban and trying to come up with a build plan.
I need advice on which suspension/brakes/steering would be best for me.

Here's a list of things that may have an effect on my decisions:

I will be using this to tow our vintage camp trailer, hopefully long distances.

I want my wife to be able to drive it so PS, PB and automatic trans. are must haves.

I want to do a 5 lug conversion and will be using 18" or 20" wheels

I would also like to mildly lower

Thanks for any advice, I will start a build thread once I can actually start to work on it.
