Dean, if you have angle grinder, the same spanner tool that is used to unlock the grinders disc lock nut works great for adjusting the 8.25

I have two angle grinder Y spanners here with dowls. One with dowls 1" apart and the other 1.25" apart.

Both work perfect for turning the adjusters of the 8.25 rear from the back of the rear.

If you dont have one you can buy a El Cheapo Harbor freight 4.5 or 5" grinder for about $15 bucs. And get Both the Grinder and the Y spanner tool to adjust your 8.25 rear. mike
