The bolt holes look be in the right places, don't want to delete the GM transfer case skid plate and don't really want to buy a replacement transfer case skid from AVE. Emailed AVE on this issue and they told me the engineers hadn't tried the AVE transmission skid with the GM transfer case skid in place, but they would likely fit together. I expect there's not a lot of motivation by the company to actually try this combo since they are selling both replacement skid plates.
