i have emailed AVO, to see what theyll say about this, because like chefrace said, the material used require ALOT of excessive torque to crack this. i torqued to 13 lbs, which shouldnt cause this whatsoever.
in the mean time, im taking to a shop tomorrow to see what theyll say. the crack isnt an issue because i know it can be welded. but making sure the flange is flat is the real challenge
