Speedo Gear...How and where do I get the correct one? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just changed Rear ends in my 1971 Cheyenne. It is a 402 big block with a 400 turbo hydramatic. It HAD a 3.08 posi-trac that I switched to a 4.10 posi-trac. What I need to know is how to find and buy the correct speedometer gear. I also have a drive line vibration at about 30-40 mph now that was there before the rear end swap but it came in at 40-50 mph. Before I switched rear ends, I have had the engine and trans rebuilt and reinstalled this spring(I have been busy) Main question I have here is where and how do I go about finding out the correct speedometer gear to get the speedometer correct again?

Thanks
