my alternator went to **** and i finally got it removed (a real pain in the ass!!) and the cost of a new for $170 is just a little to much that i am willing to spend. the local yard has one for $30 (only 34k on the car if that matters), but one of the mounting points is cracked. he said he could use the housing from my alt, to replace the bad part of the one they have. my question, will this effect the integrity of the used alt at all?? advance auto said they would test it before i attempt to put it back in, but i have to question if this is possible......thanks in advance for anyone that can reply.
