Hotchkis leaf springs sagg brand-new

Sorry for dropping off the map, busy week at work, then this weekend was the 14th(?) annual Lake Mirror Car show in Lakeland, FL. I fly out for the week tomorrow morning for work, but I will be sure to get with you about these springs.

And I think your right about my pinion angle, I think I set it at 5 degrees, which is what my driveline needed. I don't know what it is now, I don't have an angle finder up here (our shop is 2hrs south of where I live). However, even if I was at 10 degrees of pinion angle, that's under 1.5 inch difference in height at the u-joint than 3 degrees.
I did some quick statics on the springs, the torque imposed on the leaves from the engine/diff is minimal in comparison to even a small bump from the snubber, this has to be the cause. With that being said, I never had as much clearance as you are showing Dan with the A-body in your pictures (ESPECIALLY since there are 2" blocks on it??!). What u-joint is on that driveshaft? The closest my driveline comes to the floor is the u-joint, I don't think I ever had more than 2" of clearance, and that's being generous (I have 1350 u-joints). Your suggesting that there should be 6.5" clearance(taking the blocks out)? -Never, ive even bashed the freshly painted floor in w/ a hammer at this location to get that.
I don't know what conclusion or resolution we will come to, but I do know I will not be putting another set of leaf springs on this car.
