When you install an SYE and DC shaft, you have to change your pinion angle for it all to work properly. Tilting your pinion up results in upper and lower spring perches no longer inline with each other. (the spring will have an arch in it, and the bumpstops most likely will not line up.)
I moved my stock uppers when I did my SYE and axle swap.
