Upper control arm advice

I'm looking into this type of UCA myself. I have a line on a complete used front suspension with some "adjustable" upper control arms, I'm not sure but they look to be Hotchkis. It seems that the only way to adjust them is to remove the eccentric bolt and screw them in and out, which seems like a lot of work to get them where you want them past the stock settings. Another thing I noticed with the exception of the QA1 arms for the A bodies is the absence of bump stops. I know they are attached to the frame and the QA arm looks to have a tab to make contact.
Do the other brand arms factor this into their design?
