Most aren't level due to either bad advice from some or not following what others have done and it workedThey have several to pick from:

Which ones do I need?
I think I will order four of them anyway, though I think your advice makes sense. The main reason is that they are only $25 a pair and they will give me the flexibility to adjust things here and there if I need to. Despite my many questions, I have read a lot of lift threads and seem to recall a lot of people coming back after they are done wondering why things aren't level, or something like that. For little stuff where there is some debate as to how many to use, having a couple spares won't bother me as long as they are not outrageously expensive.
Pretty simple really
with no extras, then no rear upper iso's
with either top plate or clevis one extra upper
with top plate and clevis then 2 upper iso's per side
