So I had my lower intake taken to the machine shop to be tig-welded and a new hole drilled for a bolt because it was cracked, so I get it back and mount it on the engine, I go to put the upper on, and UHOH the bolt dosent go in, those rat bastards drilled it out of alignment by about 3 bolt holes, at this point im not taking the **** off again, so I had it towed to the machine shop to have it filled in and retapped and drilled, ARGH! so angry!
