Frame off restoration

[Rags63]

I have started a restoration on a 63 that has been passed down I originally pulled the body to weld in a new rear crossmember. One thing led to another and now in the process of a full restoration. Things i have done so far. Striped the frame down painted it. All new suspension bushing front and rear new hardware rebuilt rear end 

My plan is to run new break/fuel lines finish up the steering tuner disk breaks front and rear new exhaust.

Looking for some advice on things to do before putting the body on. Also what should I use for rubber between the body and frame? Any advice is greatly appreciated thank you here are some photos of the progress
