In case anyone runs into this same issue, I used a fully threaded 3/8"x3" bolt with 2 nuts and 3 fender washers. You should probably use a 2" long bolt...I had to chop off about an inch since the bolt was really close to the diff.
It sounds just like stock except a little louder. Can't tell with the window up unless you turn the radio off. There is a noticeable increase with the windows down. I dropped off my OEM exhaust at Soul Speed in Austin to do the OEM mod covering the large perforated section. I'm going to try the OEM mod and then decide.
