Going under the front end for the first time, I understand the 2x4, floor jack, theory, my question is when I get it up in the air can I use the little ramps you get at car parts stores to slip under the wheels? I like them better than jack stands, they give more vertical clearance, the stands are not in the way, and I think they're safer. I ask first because they're loaned out and I don't want to chase them if the idea doesn't work...does it? Do the exhaust tips hit the ground if you raise it that high? Thanks, Les
