O.K. My wife just bought me a 71 Chevelle for our 10th anniversary. Seems to run great although there's some noise in the rear end (sort of humming at different speeds). The brakes aren't working well and the back end seems to be sitting low. I am totally new to working on cars but know a lot of people to help me out. I'm looking forward to this learning experience but am not sure where and what parts I should get. I'd greatly appreciate any and all suggestions!
