Yes, you can do it with all stock parts.
I agree with Bob that if you're replacing parts anyway you might as well go with Moog so they'll last longer.

fyi  I used all Moog Frt end parts. Got them on amazon free shipping/no tax.   NAPA said they had them. But when they pulled them out of the warehouse they were china/mex parts.    

Drop it more than 1" and you need to address the balljoint operating angle.  Shelby used to drop the race cars even lower, like 1.25" or more, and found the ball joints would bind and live short, unpredictable lives.  As stock parts were mandated I believe their solution was to relieve the balljoint housing in a mill to gain the needed clearance (couldn't be seen with the boots in place).  This weakened the ball joints, but apparently was a better option than allowing them to bind. 

The angled shims, etc. are all designed to address the operating angle of the balljoint, but its a myth that you need to do anything on just a simple 1" drop.  All the issues reported were from Shelby's racing program.  Like most myths there was a basis in fact, but the guys retelling the tale over and over lost the origin of the story, and it became a "fact" that any time you lowered the UCA the balljoints became an issue.
