Classic Car bar badges 

I hope Sir "Grumpy" is feeling better, did a very nice job!

I think that looks ok, fiddly job, glad grumpy is better

I think you said at one point, aren't the brackets a standard size?? I think they didn't tighten up because you had the badges in between the 2 flanges of the brackets, meaning it wouldn't tighten up enough. Try and fix the badge either behind or in front of the bracket. HTH
