OK, I went back to my left over stock and was able to fabricate the following from what I had left:
It's 5/16" shorter than planned. Anyone have an opinion on this? Acceptable?
I think your new bracket looks fine as long as you have enough edge next to the rivet hole.
If you would prefer I do have a piece left from my goof.
Let me know, I could ship Thursday but I am out of town tomorrow.
I just measured mine and it may not be any better than yours. The usable inside angle length is 3.75".
Let me know I will check this thread in the morning.
