The rear bar is hollow?!
That is surprising. I didn't think so because it is so small and if you bang it with a hammer it sounds solid. ....not the hollow sound the front one makes.
I searched the Saner site but they don't list a bar for Bonnes. I tried asking them but they didn't reply.
I don't know about the bar bushings.
maybe i got the cheap version because there was a WORLD of difference between the Saner and Stock. i will have to go and weigh the stock one - it'* stll in the garage. I could NEVER get a response from Saner either ... i ended up buying mine off of Scott Cook.
