Hey Chris, welcome! My first R started off as a Frame only and it really gave me an education on what they're all about. However, I believe buying a complete R and taking it apart for rebuild would do the same and be cheaper & less time consuming, depending. I say "depending" because if you plan on going completely aftermarket, or even mostly, you just bought a bunch of parts you don't need.
What's your Plan? Oem resto, resto-mod, or full aftermarket?
