TrailBoss with Rock Tamers

[Gutzy]

I recently purchased rock-tamers for my 19 Trail Boss and I currently have a generic Curt 2" Trailer ball hitch. problem is that I don't have the required 1" gap for the rock tamers to sit. has anyone else ran into this issue with the trail boss or the new Chevy's. I'm like 1/2 in short and if the pin would slightly be back it would make it. I really don't want to spend a ton of $$$ on the multi ball drop hitches as i only tow things with the 2" ball. want the max towing capacity to be at least 7500, 750 tongue weight. Any recommendations out there or have others ran in to similar issues.
