I like what Icon 4x4 does on their Derelict projects. They basically update/replace everything, except the original paint.
Yep
My son has a 77 4 wd Stepside chevy .
He’s swapped in 3/4 ton axles , a NV3500 five speed , a Fuel injected LS ,
Vintage air hvac , four wheel disc brakes , new springs and bushings , new steering box etc etc
But the paint hasn’t had any attention,
It looks just like it did when he bought it from a ranch in Arizona ten years ago.
We did find some rattle can color that’s a good match to the patina ,
