Truck Forums - Road Armor Bumper HELP

New to the forum and wanted to say hello to everyone,
with that out of the way I have a little problem that hopefully someone can help me with
I recently purchased a used Road Armor front bumper for my 2003 2500HD but unfortunately it didn’t come with the mounting brackets. I have a friend who said he could fabricate a set for me but with the bumper weighing close to 200 pounds it’s not the easiest thing in the world to hold the bumper in place while he tries to figure out the measurements. So I figured it might be easier and simpler to reach out and see if anyone has one on their truck of similar body style and wouldn’t mine sharing, could you take a picture of it or sketch it out and possible give me the measurement specks on them. Thank you guys in advance for any help.
