This newly designed adapter plates will allow you to bolt a Gen 3 or Gen 4 LS engine into the place where a 4.3 V6 came factory. The 2000-13 Chevrolet and GMC trucks use a different front cross member that is welded in and do not accommodate the factory LS engine mounts. These adapter plates bolt to the LS engine and re-use the factory V6 engine mounts. CNC laser cut from .375 P&O cold roll steel. Grade 8 bolts and washers included. This is a set for left and right engine mounts.  You will no longer need to use the factory V6 motor mount spacer plates. These are not adjustable. 

* Raw steel- Black texture powder coat is available.

* Will not fit DART aftermarket blocks.

* Reccomend using a 1998-02 Camaro F Body oil pan.
