Pole Position A-arm install questions

[whytry]

I recently purchased the Pole Position A arms, (SPC performance) part numbers 94302, and 94303, for my 68 Camaro, with the Mook K5208 ball joints. I have stock disc brake spindles and could not get the ball joint to sit down low enough to close the gap on between the spindle and the A-arm. I used the spacers that come with the A-arms and got the gap to close. Upon completion of the install in the car I noticed the car sits about 2.5" higher in the front than it did with the stock A-arms.
Has anybody else had this problem?
Also the directions show one for left and one for right, but how do I know if they are sitting in the driver seat when they mark them L,R or standing in front of the car looking at the headlights. I tried putting the A-arm over the stock ones and if you flip them over either one will go in either place...
Please help....
