It’s already been mentioned, the steering wheel and wheels are the most replaced items.
I tell people my truck is 90% original
When I bought it in ‘92, The Steering wheel had already been replaced with a Square body one, and the rims were White spoke.
On the engine, the carb and manifold are aftermarket, and it’s got headers instead of manifolds.
I’m about to refresh the paint, and replace the bed wood
Other than that, she’s factory
Not shortened, not lowered, not LS swapped, not tank relocated, not painted a non factory color, and the interior is not molested.
Whenever anyone asks if I’m gonna do anything, my response will is “Why mess with perfection?”
