Okay, so I've already had my expo 8.8 perches rewelded, then I found this:
Now, couldnt the same basic idea apply, I mean everything done here except the opposite.
Use the flip bracket over the expo axle to sit in the perch. Instead of here where it goes under the axle.
Maybe I make no sense but I though it was an interesting idea, and I'm probably so wrong it's ridiculous, but not looking at the axles side by side, I don't see why it wouldn't work.
