After reading the posts several times, I took some measurements on my A122, based on what I could see from the couple of pics and a youtube video.
I think the 30" actuator will work, if the lower base mounting point is moved lower, and possibly using the bottom trim existing screw just in front of the coolcat. At the top, the mounting point will depend on where the limit works right with the roof raised. Worst case scenario, I think, is that I might have to add an aluminum plate to add about 1.5" up beyond the existing top edge. No big deal.
I will report on my project, although it will probably be a month until completion.
Wish us all luck!
