MY Blazer started making some very bad sounds yesterday. I just got out form under it and found that the fly plate is broken in two places. /forums/images/icons/frown.gif here are my questions: #1- any way to replace it with out loosining everything up and moving it back? #2- got 2 different prices....one for $13.99 (Auto Zone) and one for $31.99 (form a small independent place).....any difference in quality i should be concerned with? #3- Is this common? #4- what usually causes this to happen? Thanks in advance!
