Nothing pure about adding what wasn't there. Do what you want to your own truck but be honest about what it is if selling. To some, it's a plus to have all the bells and whistles even if they aren't original. But a purist will want it as built. I don't think it's a purest thing, it's a true collector thing. A truck that actually came with all the goodies, or a unique combination of, is a stand out truck compared to one that had it added. I think there are fewer who would be honest about the changes than those with the level of integrity to disclose. We see it all the time on Ebay.
