You might start prepping a week or so ahead of time. Use liquid wrench on
the bolts every other day to dissolve the rust.The bolts usually are not
hard to get out. Use a good quality 6 point socket if you can. If SAE is too
loose try a metric, even if you have to tap it on. work slowly and don't
apply too much force. I've never had a GM bolt fail to come loose. Fords
are a different story.
