If you're using it at 300mm...the tripod collar from the AF-S 300 f4 will work (w/teflon strips)
I did the mod on one I found on the B&S here for $35. Guys get the Kirk replacement, and often sell the OEM.
However, you'll still have balancing problems...it'll work with better a BushHawk.
Don't have a pic handy of the 70-300 collar mod and the BushHawk, but here it is shown with the StedyEddy.
**This could work with the Sidekick if you could live with the aforementioned balance issue.
(just add an A.S. lens plate)
