Tubular A arms slightly too wide!
Good grief!:rolleyes:
Call CPP before you do anything. If it was a jig issue you may not the only one with a set like this, which also means they may have already heard of this issue. You bought them second hand so they may not do anything about it, but who knows. Worth a shot. They certainly won't do anything if you alter them.
Outside of that, I'm not going to recommend altering them to fit. I'm not saying it can't be done, I'm not even saying I wouldn't try it myself, but I'm sure as heck not just gonna say toss them in a press to someone on the internet without seeing them. Tubular arms are used because they don't flex that much. They have welded joints that could fail. Yeah you can probably get that much out of them without screwing up the geometry. But if the weld fatigues without fracturing you might find out 5 years from now when it fails. No thanks.
