Here's the solution I used. Generic Amazon mount specific for Uniden R7. Blendmount did not have anything available at the time of install. Power tapped using a Dongar adapter.
I got it from Walmart for $20. It's the same dimensions as the Husky container from Home Depot which most people use. I actually had the jack in a Husky container but didn't like the red so I returned it.
Received & installed my replacement lid today. @SXTH Element sent me a new one even though I purchased the intake from a forum member. Great customer service.
Noticed the dents on my donut spare a few weeks ago. Last Sunday I checked and the full size spare has dents forming as well. I ordered a 1/8" thick sheet of abs plastic and cut it to size to act a as shield. Let's see if this helps. Will check again in a month.
