Amazing how much space all the parts occupy until you package it all back in the car. I'm finally finishing my 1965 Dart. I spent the most time on finicky stuff in the interior and dash and the fussy exterior trim of my GT trim. At least only missing a few trim parts, and might even have those stashed somewhere. I'll look closer once I put my just-repainted 1985 M-B back together (also confusion of parts). You can spend a fortune if buying "correct" parts for everything like trim attachments. Often you can do cheaper and better than the OE design by leveraging generic parts or for a GM. I use stainless fasteners from Ace Hardware wherever I can. I had most OE fasteners. I cleaned corrosion by soaking in Evap-O-Rust, then phosphoric acid to convert any remaining rust in pits, then painting. I did in batches, shaking the nuts and bolts together in a jar with soap and water, multiple times to remove all debris. When rushed, I at least spray fasteners with Rustoleum Rust Preventive. Might start using Fluid Film under all my vehicles, though minimal corrosion concerns in CA, though chrome plating usually pits everywhere.
