Briggo Dirt Deflector Help!

[Jonno 0]

Purchased a briggo deflector which fitted my bike perfect. The bike had a curved back end and the spindle had plenty of room to allow moving the wheel back and forward as i wanted.

 

I have now changed the back end to a straight one and upon putting the briggo back on i can't move the wheel back far enough. The straight back end is like a V and at this point the briggo spindle wont slot in the gap without moving the wheel right forward resulting in a slack chain?

 

I need to know weather I should grind a bit of the spindle to allow it to fit? I don't really want to shorten the chain if I can help it. What does everyone else do? Advise would be appreciated. Cheers Jon

I had to re shape mine when I changed back ends. You need to cut a bit off it.
