Seems to be quite a bit to it. I feel dumb because I had a complete 71-74 ralley dash set up I bought from a neighbor years ago because it was a good deal. Did not think I would ever use it. So one year (before any of this or before I knew about ebay or craigslist) I took it to the Nationals and sold it to a vendor just so I could have a little spending money to buy stuff for my newly acquired 78 Lil Red Express. Obviously I did not know what those things sold for as I practically gave it away. I see on the RTE website that they appear to sell complete Ralley dash set ups for like $2500..ouch!
