i got lucky today
 

if you remember a while back i changed the trailing arm on my 300sd. well when i put the caliper back on one of the bolts wasnt tight enough and fell out. well this caused the other one to become loose. i went to back up and the tire stopped and the back end jumped up in the air. as i turns out the bolt fell out and the whole ride home the caliper was creating a groove in the rim. when i went to back up the caliper hit a deeper part of the grove and was catching. luckily i had a spare bolt. i just thought i would share my experience with everyone.

i also filled my ac system with r12. a few people told me there was more wrong with it than it just needing freon. well pulled a vac. held it and then filled it with r12. blows cold air. now if i could just get the main vents to work.

give us an update next month at this time.

Ditto to what Frank said. It was low on R12 for some reason.
