Getting Things Ready For 1969 Barracuda

So I'm finally at a point in my military career where I can start to refocus on restoring my barracuda. I'm having the car brought down to where I currently am, I have a local body shop all lined up to do the metal work and paint. While that's away I was going to try to get everything I can together so whenever the body and paint are done I can just bolt a few things in and be ready to go. My question is for anyone who has more experience with barracudas than I, What can I assemble now so that reinstallation will go quicker, I.E. grill, dashboard, etc. and just overall any advice you have on restoring a barracuda properly. Thanks.
