Maybe I should take a pic of mine while I have it on the lift next week.
I used gussets just like you did, but I used scrap metal I had around, so they aren't all identical in size

Nice work, but Tom is correct about the keepers! My mount is hollow at the sides. I guess you could just use a hole saw to fix that, buuuutt.....
