LMC fender patch panels

[HRD]

Was wandering if anyone has used these lower front fender patches from LMC. Listed as item #1 under Steel Body Patch Panels here. http://www.lmctruck.com/icatalog/ca/full.aspx?Page=10
The catalog lists them as Chevy only under Applications. I emailed tech at LMC and they responded that if the catalog doesn’t list them for GMC they could not guarantee that they would even work for my propose.
I’m thinking that they will work but just don’t have the park lite hole punched that a GMC would need. I do not plan on needing to go that high on my fenders for what I need to patch.
What are some of you’ll thought? Thanks for the help.
My areas I need the patches for. Both sides are about the same.
