3/4 ton front driveshaft - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was wondering if the drive shaft on a 1970 C/20 4x4 is suppose to be the small as the one on the Blazer. My 3/4 ton front driveshaft has only 2 U-joints unlike my Blazer which has 3, 2 in that CV style joint. Any knowledge would be appreciated. Reason I am asking is, I just bought the truck and have discovered a few re-engineered items that make me question things that look suspicious, and the welds on the front drive shaft don’t look like what I am use to seeing on 1970 trucks.
