All threaded holes in the block and cylinder head should cleaned and tapped with a thread chaser. All bolts being installed should be lubed with a light oil or anti-seize on the bolt threads before assembly.

When installing this bracket on truck engines the upper hole is not drilled or tapped in the block.  Aluminum LS1 blocks will use three mounting holes. Trucks will only use two, one upper and one lower.

Using the Dirty Dingo front bracket turned upside down place a transfer punch through the upper hole and mark the block.

This should be drilled with a "R" .339 drill bit 1" deep and tapped with a 10MMx1.5 flat bottom tap 3/4" deep.

The middle hole will not be used on the truck engines, only the top and bottom holes using the two short "A" spacers with an alternator from a 1998-02 Camaro. Mount the billet rear brace as shown.  Camaro-GTO applications will not use a spacer between the alternator and the rear brace. This photo shows the rear brace on Truck spacing.

Mount the pulley on the front of the bracket.

If you are installing a combo kit with AC- use the AC install instructions for correct belt size.
