Looking for a little help from anyone with a rear Mopar Hard Rock bumper-

I just bought one on CL and its in great shape, all parts included- with the exception of one that I missed...

If anyone can tell me the thickness of the spacer that goes in between the tow harness screws and the bumper, it would be amazing. From Mopar the piece is $55... For a piece of metal with 4 holes in it, seems excessive! I think I can fabricate for a little less.

I can't imaging its too big. 1/4", 3/8"? The picture sucks, I know, but it's part #9 in the diagram-

Thanks for the help!

 

I've got the bracket in my tool box, I'll have to go look at it. The stock hitch takes up that gap. For $55, you could buy a hitch and have the bumper plus hitch.

 

I have a hitch from the factory so I should be good- thanks!
