What kind of Posi do I have here? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Pulled the covers to check ratios and I noticed the rear diff. looks to be a posi? It looks different than my 71 (no clutches) is this factory or aftermarket? Oh and i'm planning on running 35's with either the set that came with the truck(3.07) or these (3.42). Yeah I know that's pretty tall gearing for such large tires, but I don't plan on any rock crawling in this truck. Will I notice a huge difference between the two ratios?
