Ya just had a set crack checked today. Got to get some more components and get another one together. Had carrier deflection before when running a welded unit. The quaife is a much more rigid unit. No cast and no windows. I also found bmc flywheel bolts from arp that have oversized shanks that are almost a press fit into the carrier. I got those going after the first bolt failure. I've found that having 8 bolts I can only get the ring gear on in one position. I'm guessing I'm matching up a half a thou. of mis machining between the ring and the carrier. So I'm very confidment in the in how rigid that is. Otherwise carrier caps are sucked down with arp studs and timken bearings at a .005 bearing preload. The diff case is all cast iron and the 2 halves together with a whole bunch or arp bolts getting full length thread engagement. I happen to have my c3 vette diff built and on an engine stand at work....I keep looking at it but it's literally 3 times the size of what can fit in the car lol.
