TODAY is a Great Day to visit our Store and order the parts you need for your truck ! ! !
It depends on what part you are looking for. I would say as far as body and sheetmetal, either from another truck or on this sites store. Most from the catalogues do not fit well at all. If you are looking for something found at auto parts store then local would save you shipping.
rock auto has a great sitefor certain items, electrical components for ex. i would try to get original ac delco if possiblethere are many companies which sell parts for the older trucks,their catalogs are a great reference tool. but be aware you will find most stuff on the "pricey" side. a few years back i replaced my tank and needed the fuel filler and vent hose and i was shocked at how much they were.if i were looking for certain 73-87 specific parts ... i would consider getting the parts from this site, simply for the sake of supporting the site as i find it to be a great resource of information.
