Welcome from So. Cal. I would suggest that if it’s mechanically sound, get it outside and play with it.
Looking to do just that, just ordered some budget minded Pro Comp shocks, 285/75R16 General Grabber ATxs, 2” leveling kit with 1” blocks for the rears, a Summit Racing cam kit and thinking about rehearing as we have a car trailer that we haul periodically with it. It is a 6.0/4L80E combo with 3.73s, and old fire rig out of Saint Helens Oregon.
My family lived in San Dimas in ‘91-92, I went my freshman year at Lutheran High La Verne, loved living close to Pomona and hearing the dragsters. Nice little town.
