Rear Shocks and Coil Springs, 1970 c10

[Eric1970]

Morning, all.

I have the driver side mounted, with the exception of having the spring tightened up. The spring is set at the top, although needs to move forward on the bottom.

I am considering removing the passenger side wheel as well so I may jack up the rear to seat both springs at once. I have jack stands supporting the frame just past (behind) where the trailing arms meet the frame, and am just a wee bit nervous about removing both rear tires at once.

A friend of mine is convinced I'm missing rubber bushings that help seat the springs, however, I didn't see any on it when I pulled the old springs off. Any truth to the missing bushing theory?

Any tricks or tips would be much appreciated; this is taking me way too long...
