this is a easy job, 5 minutes max for both sides.. they just pry off w/ a
little tiny flathead, or i use a plastic putty knife so i dont scratch the paint.
 just pry off that trim cover that covers the joint where the horizontal
window scraper meets the vertical side scraper..

when tapping them back in, i use a long piece of wood laid horizontally over
the length of the scraper and a small hammer..  the long piece of wood
disperses the impact from the tapping so it wont bend the scraper as u tap it back
in. ..

ps, like i said before, the inner scrapers are the same as the outer ones..so
just get some good used inner scrapers.. they inners rarely go bad.
