I have an '09 Summit. I would like to put longer adjuster bolts in the primary for the quick clickers to attach to. I have been told to use newer model year bolts. When looking up the part #'s, the '10's are a different # than the '11's. The '11's are $4 cheaper than the '10's. I am doing this to 3 sleds and that $4 adds up to quite a bit. Can I use the '11's or do I need the '10"s? Thanks for any help.
