thanks for the input!

i've read more about options and have the following possibilities for raising my wagon's rear end:

1) restore the sls (missing struts, so will wait till i win the lottery)
2) add shims (may not add desired height)
3) replace springs with w126/w116 type (i assume rear springs)
4) monroe air shocks

i have a question about the air shock possibility--if the springs are supposed to normally hold the vehicle's weight (or most of it), will the air shocks actually raise the vehicle and support its weight for regular use? or is it too hard on the air shocks to keep it lifted for the long term?

i'll be measuring the current shock dimensions this weekend and will find out if monroe has an air shock that will fit.

picture attached that shows the sag. i will also measure the hubcap-star to wheel well distance (should be 12.5", right?) this weekend. [Edit, this is incorrect--should be top of hubcap to wheel well)

thanks again, more soon.

Measured top of hubcap to wheel well at 9" [added info]
