i had to trim the stinger tube on the left side only, to get the bolt holes to line back up. I PM'ed duner just to let him know, and he said he'd make me a new set, but trimming the tube was no big deal to me. Oh these were on my Fatty's, not rockets...
here's a pic of my clamps from duner
pipe clamp pic <clicky
