I have to adjust one of my doors also but for the life of me I couldn't figure out how to access a couple of those bolts. I couldn't get a wrench on at least 2 nor could I get an extension in there. Do you use a wobble ended extension or is there some other trick to getting to these bolts. I sure don't want to pull a fender but I just can't see how to do it.
