This does not use any pins or grommets to hold it in place because it has 2 tabs molded into the sides which snap into the holes which the above grommets used.
If your flapper currently has round grommets that hold it in, and a 4 inch Y-Pipe, then this is the correct flapper If your current flapper is held in with square grommets, then you need 807166A1
Does Not Fit 4.3 Engines Originally Equipped with the 1 Piece Exhaust Manifold
Fits 1982-1996 engines with oval 4" Y-pipes with round pin holes
