Rated 5 out of 5 by from Hard to fine, but found it at Pep Boys I am the original owner of a classic 1968 Firebird 350, and sometimes fine it difficult to get parts and maintenance supplies. If I go to an exclusive online or speciality store the costs are high. I have always found the parts, etc. at Pep Boys to be reasonable and fair and the staff extremely helpful. Sometimes they want to see the car. I care for my car, and do the small maintenance jobs myself.
