I would do like i did to rusty 2.0. Fix it up in stock condition...no fancy swaps or anything.
I get that some guys like modern stuff shoved in old vehicles, but to me it ruins its soul. Its just another vehicle with a better looking body.
I'm exactly the same way. I love these old trucks the just the way they were built, and that's how I keep my "collection". But, I'm also very interested in what the off-road AND the street-custom guys are doing to their trucks. I have a lot of respect, and admiration, for a well-thought out build or modification, and I love seeing good old-fashion craftsmanship. There are people here who are honestly mechanical artists.
Someday I'd like to see someone build a Bronco II with a modern drivetrain and suspension and make one like new.
And I can also understand taking a classic design (the dearly departed Bronco II is coming up on being 36 years old, after all), and modernizing the drivetrain, suspension, interior and electronics. Even I'll be the first to admit, the comfort and driveability of classic cars (trucks) and new cars are like two different worlds.
Here's food for thought. Can you imagine a display (say, at someplace like SEMA) consisting of these three vehicles:
1) An early Bronco II, restored to "day 1" stock as-left-factory condition, brand-new clean and sporting its window sticker.
2) A new 2020 Bronco II (is that even what they're calling it?).
And right in between them:
3) An early Bronco II body, on a modern or trick better suspension, with the new drivetrain, and with the modern interior and all of the electronic gadgetry.
All in the same basic paint scheme.
