- Body Mount Bolt Information (1982-88)
There are three different size bolts.
Position 1 uses GM P/N 10049638 (sold ea., 2 needed). Bolt is 12 X 1.75 X 95mm long.
95mm is not common so you have to use 100mm.
Position 3 uses GM P/N 14085301 (sold by pkgs. of 5, 2 needed). Bolt is 10 X 1.5 X 55mm long. Also need two nuts.
Position 2, 4, 6, 7 uses GM P/N 3524497 (sold by pkgs. of 5, 8 needed). Bolts are 10 X 1.5 X 80mm long.
I bought the bolts at Spaenaur and was able to buy the quantity I needed and not the whole package and the reason why the bolts seem expensive they are....anything metric is ridiculously priced
