little rear overhaul at home

hang an old blanket or towel, or use painters tape, and cover up the inner fender to keep from scratching the paint.
I scratched the body, really when taking out the exhaust manifold. you are right, it is necessary to protect much better. my blanket fell just as I was going against the bodywork.
the most difficult is to see the collector practically out, but you have to climb the car another 2 centimeters.
