Educate me on leaf spring uprights

[MAStuart]

HI. Thanks for the responses so far to my post. Yes, that is the drawing I was referring to. That is what I assumed the bosses were for, the bearing retainer. The drawing appears to be for a spline drive hub, that is why I want to know if they are machined different for a spline drive vs a pin drive? Or are they just machined different for the bearings? In the drawing the outer is mostly captured in the bearing retainer, the inner bearing, outer race floats in the uprights. On my castings, it appears to take the outer bearing and seal without using the bearing retainer. So far that is all I have purchased is the uprights, front and rear. I am assuming it takes tapered roller bearings like Mickmate said, with a spacer between to set the preload. Yes I know these are not original uprights, but were uprights machined this way and used on competition cars.

My next question is, how many different people manufacture original style, leaf spring uprights? Not people who resell them, but actually manufacture them.

Does anyone have a good picture of a 427 front upright? Hey Mickmate, is the front upright itself longer, not including the way it is attached to the upper control arm? I am not sure how they are, if they are similar to a leaf spring one with the upright and a seperate clevice attached to it? (a separate part that the ball joint attaches to?)

Does anyone have a picture of the type of clevice that member CSX1885 is using on his leaf spring build? I think they are from Shelby. They appear to be adjustable. Thanks. More questions probably to follow. Mark
