Yup, pretty darn close to hollister....let me know!
Well, back to the real question. Since you are in California, and I assume you live in a county that requires biyearly smog inspections, I would go with a 87-91 with TBI, or a pre-75 rig that will be SMOG exempt. It's just easier to not deal with it. I swapped on a TBI to replace my computer controlled carb so that I could pass smog. Other than motors, and transfer cases, there really isn't much different from year to year. The look changed from generation to generation, but they are the same basic truck. Which is great because finding parts is really simple.
Best places to check for nice rigs are on this site, pirate, and the norcal and socal bigdawgs sites. There are a few out in the classifieds too. Many can be found with newer crate motors installed.
