Some Grizzly machines are knock-offs of
Powermatic designs, but I don’t know if
the similarities are enough for jointer fences
to be compatible.

Another suggestion:

I had a Walker-Turner jointer at one time
with a fence that was missing some parts.
Rather than trying to fix the fence I make
my own center-mount tilting fence using hinges
and plywood. It could do angles but the hinges
had a little too much play for it to be really
reliable. I eventually repaired the iron fence,
which was still kind of lame. If making your
own I would suggest forgoing the tilting feature
on the first try at least.
