clearance under mustang II crossmember

Anybody know what the clearance is under a mustang II type crossmember and the pavement. With out drop spindles and about a 26 tall tire?

 

How much load, what springs/rate?

 

between 9" 10" give or take IF you have the lower arms parallel to the ground.

 

I just tring to figure if I would need drop spindles before I buy any thing. I'm thinking arms level, Thanks

 

the lower arms NEED to be level... thats the way it works to get the right suspension travel
