At least with the Baja's, the only real option without carving the TC plate up a bunch is the way we both have it mounted.
A slice still needs to come off the bottom to clear the frame.
I've found that even using good chain, but leaving about a half inch play in it, the chain will still bounce against the frame.
The nice thing about a tensioner, is that it gives you a little more time between chain adjustments.
That's me. Always going against the grain.
