im planing on doing the hagen widening and rotate mod. but have a question about the 3rd link. do i do the same as the rock sready lift. i only have 1" coil spacer

When I did mine in order to get the correct angle on the driveshaft, and get the advantages of the overation, such as moving the axle back a bit my center link spacer had to be offset to work.  The bottom 4 bolts of the spacer that bolt to the top of the diff and the top 4 holes that bolt to the center link only share the hole spacing in the middle holes. --   something like this if your looking at the spacer from the side.  Hope that makes sense.                                                           --
                                                                                                                                   

is this mod even worth it with only 1" of lift? also is the widening mod not a good idea on a daily driver?

with only 1" of lift it's not really necessary, either is the whole widening mod if your using it mostly as a daily driver. there are some great advantages to doing the mod, especially if you want to run bigger tires, 32/33", but otherwise, IMO, no.

i thknk i might just do the rotate mod for now. if were to raise the spring mount that should give me a little lift in the rear right? my rear end sags alittle as it is so that should help

You'd probably be better off just replacing the coils, the diff rotation isn't going to give you any lift, and with sagging coils you might actually loose a bit. Raising the spring pad is a way to get some lift, and you have to cut them off when you do the rotation and re weld them anyway, it may help.
