This is a new top quality correct air cleaner lid only - does not include bottom or seal. This is not the Chevy lid that has been on the market. We at The Parts Place have made a correct 17" lid to replace your 1968-75 Firebird Formula; 1968-72 Cutlass / W-30; and 1968 -72 Skylark GS models. It is manufactured for The Parts Place.
