Unacceptable: tubular upper control arms with no bump stop pads.

Just my 2c as well. I purchased the same UCA's from PST, and can confirm the right side does not simply drop in. This arm not fitting without forcing it into position caused it to bind enough to break the cam from the adjustment bolt when trying to set initial position. I replaced the adjuster and have it bolted together but have chosen to do other work on the car and will address this issue later. In hindsight, I would of gladly spent the extra bucks for different UCA's. Greg (Bergman) was pumping their adjustable flagships at me for a bit, but not in my price or requirement range at that time. Nice stuff they sell...
I think a measurement like MV8 posted is in the future. it looks like the location/angle of the forward bushing is wrong.
I am curious if PST would correct this, or would I receive the same response on the ball joint boots that won't compress into the cavity. "That's just the way their made". I did get Moog to send me different boots that fit perfectly, so a non issue now. But that's a different story.
