Addco sway bars

I bought a rear Addco bar from Summit. The bar was designed for an 8-3/4" rearend but I have a 7-1/4" which is stock with the 6 banger. Anyhow the hardware didn't fit properly and nowhere on Summits site did it specify which rearend when ordering. Of course by then I had everything ripped open, parts scratched etc. so I couldn't send it back. I had to modify everything to get it to work. On the bright side, I have the same bar on my other car with the bigger rearend and it works great.
