SPC / SC&C Adjustable Upper Control Arms - Droop Stop?

[TheBandit]

I am interested in the SPC / SC&C adjustable upper arms for my '70 Nova, but I am a bit concerned that they lack a droop stop. I realize droop stops are a bit less important than bump stops, but to protect shocks from over extension and soften the blow of (rare) offloading of the tire, I'm curious if anyone has added them somehow.



I'm also curious how difficult these are to adjust when you're aligning the car. Do the adjustment sleeves turn easily when you have the weight on the tires? Can you access them easily with the inner fenders and tires on?

Here is a picture of the arms from John's Blue Bomb thread:



Thanks for any feedback or comments.
