Refurbishing Upper Control Arms (UCA)

Your doing a great job! Keep up the good work! This is a great walk thru for first timers. I have the moog offset bushings also I have not installed them yet. So basically on the front of the uca the arrow points to the ball joint and the rear it points to the car?
I have skp ball joints upper and lower. I dont see much difference other than the boot from the moog ball joint I'm sure either will be fine.
