need help, measurements of stock height 2wd (with pics)

My 86 gmc is supposed to have stock coil sings in it, and I'm not sure it does.

First pic is the measurement from the lower a arm to the upper spring perch off frame. (Crossmember)
Second pic is from the bumps top on lower a arm to same frame spring perch. (Crossmember)

Does this resemble stock arrangements? Looks lowered to me.

My truck has 2" drop spindles, but that shouldn't affect these measurements.

Seems the suspension travel isn't up to snuff either, I'm about to replace some bushings in the a-arms with some that doesn't lock the a-arms to the chassis with the rubber link, just don't know which ones yet. Trying to transfer weight on takeoff, already have 90/10 shocks, I don't think the front end is lifting as much as it could.

Thanks

D Moss

First pic is from the top of the spring perch (crossmember) to the lower side of the upper a-arm.

Second picture is from the lower arm to the ground.
