driveshaft question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I swapped out rear ends, but having an issue with the u-bolts at the driveshaft. Did Chevy use more than one pinion size? The u-bolts dont seem to fit in the pinion on the rear end. I dont have the old rear end around to check the old one, but they just wont fit. I even tried replacements and nothing. Has anyone else experienced this, its like the u-bolts are too narrow.

I'm thinkin of tryin some Moroso U-joint girdles, I'm thinkin theyll have a little more adjustment during the install. Anyone ever tried these?
