Pics of pie'd or notched upper control arms

[powerslave]

I've got a 66 c10 on a budget and I'm trying to get as low as possible in the front without going with a drop member or tubular c arms. I just got a set of McGaugys 2.5" drop spindles and I've already cupped my lower control arms, but when I lay it out, my upper control arm ball joint binds and stops me from going down another inch or more.

Can I see some pics of how and where you guys are cutting your upper control arms so that I can correct the upper ball joint angle.
