Nice install...good write up...However, I would recommend some different rivets...
I know Oft boys do well, but IMHO, these are the best made...

These do a phenomenal job of grabbing...especially if you have had to drill a rivet out once or twice...
In your case, I would use the Yammie Blue colored Rivets...they come in dozens of colors...You generally dont need backers with these rivets either, due to how they are made...
Just my 2 cents...
