will cupping the upper bag mounts allow lca to lay flat against the crossmember

[67cheby]

I have cpp 2.5 drop spindles and strong arms and bags with air ride tech upper bag plates... its seems to me that the air bag is the only keeping the front from going down about anothe 1.5 inches, so if i cupped the upper bag plate woul it lay the lca against the crossmember or is something else holding it there that i am not seeing ??
