The RV-8 kit is a bolt in item. I added mine in while the wing was under construction. It could be retrofitted in working through one of the wing inspection covers. There is not a lot of room and there could be issues if the builder used a nut to hold a bolt in place instead of a nutplate. I used nutplates on my build so that everything could be removed and or installed with just one wrench.
The RV-9(A) roll kit
is very similar to the RV-8. I do not remember there being instructions for the install but there were lots of other builders that used websites to document their build and I printed several photos of others installed servo to make sure I got my bracket installed correctly.
