The general RoT is the older, the lighter.
Since there aren't too many pre-war prototypes or wartime cars available locally, look for 45-48s, they'll be the lightest us commoners will hope to find.
Every time there's a significant upgrade, things got heavier. A synchro 2-3-4 trans is heavier than a full crash (53-54) A full synchro (61) is heavier than the synchro 2-3-4. A 36hp engine is heavier than a 25hp. 40hp heavier still.
Brakes too. Oval drums are narrower than early 60s drums, so they're lighter.
Glass. Silas' 64 has smaller windows than Alan's 65, so his glass is lighter. But Silas' sunroof cancels any advantage.
What's the plan for this lightweight quest?
