Tubular A arms slightly too wide!
We have seen this problem before, right here on FABO.
If you draw them together with all thread, it may be that the two cam-bolts will end up running at angles to eachother. This will cause binding and premature bushing failure. So after you have successfully tweaked them to fit in there, you will have to sight them, and more tweaking may be required. Ima thinking there will be a torch involved,lol.
That wouldn't scare me at all.
