    i was told that i can only use a western unimount undercarrage from a 2003 chev 1500 not a 2500 or 2500hd or 1500hd wont work. also i was told that this year truck uses a positive ground for the plow so any unimount wont work, any body heard simmular??

    Bad info. The only thing changed was the headlight harness in 03. They use an 11 pin harness vs a 9 pin, and yes it's due to reversed grounds......but that's the headlights. You can put a Unimount on anything, worst case you'd have to switch the plow side to 3 plugs vs 2.

    Yes, 1500 mounts are all that will work b/c the sub frames on other models differ quite a bit. They (1/2 tons) are the same 99-07.5.
