Let me clarify, I don't and can't vouch for Rocky Roads. I know nothing about them. They just seem to have a lot of eye candy.
When I had a '71, I bought a few bits from James Duff, and a few more from Wild Horses. Both had good stuff, from my experience.
That said, for the money that any high end resto-mod runs, you can probably do anything yourself, or basically be a general contractor to a bunch of good subs. Early Bronco's aren't rocket science. They share a bunch of parts with Mustangs and trucks of the same vintage. There are a ton of parts and updates available, and they're every bit as cool as old Landcruisers.
Get that guy on ExPo- I want to watch the resto!
