From Carpy:
"I have had a couple do this but I have managed to find some bushings from a local shop from time to time that fits, failing that, you can send me the swing arm and i can then maybe weld another tube ring to house the bushing, As the only way that can stop moving woth STOCK bushings is to tig spot weld them in or, make some Teflon bushings.
I even had this issue on the STOCK original DRESDA I had."
Seems reasonable. #$%* happens, I'm just glad he's willing to fix the problem if it still remains. Now, I have to look for some bushings. If not I'll send it out.
