Demon rear spring height

Can I use the 12" # for my 74 Duster to set up my initial front end height? Then just check the sides? I've been sick *** heck for 6 weeks, covid to bronchitis, finally got some treatment. And moving a Lil. Wanna go finalize this mother so I can go for a ride

I don't see why not, I mean realistically you can set whatever number you want as long as you follow it up with checking/modifying the bump stops depending on what torsion bars you're running and setting the alignment (not to FSM specs for radials).

The better number to use for the front would be the suspension number though, the A-B spec'd in the FSM, since the suspension number is more important anyway. The factory didn't really give any corresponding number for the rear, which is where the bumper height thing comes in. But for the front suspension the FSM is pretty specific if you want to run stock heights...
