Can't help with where since I don't have a 22, maybe someone in this thread knows and if not ask in the 22 SCT thread. For sure someone there will know.
For the next time though, mark where your holes should be on the over spray film before you paint. Much easier to line it up while its clear and unpainted.
You can try putting a dab of grease on the top of the posts and place the body to mark where you should ream. It won't be perfect, measure to square up your holes.
