My 2004 Crossfire coupe has a bad alternator that needs replacing. I hear it's a manageable DIY job for a non pro and refuse to pay the $1100 the dealership quoted.

Thing is - most auto parts stores only have a single part as replacement. However - when I called one they specifically asked me if my car had a Bosch or Valeo alternator. Upon checking - I have the Valeo. So my question is are these parts compatible in any way or should I just buy from the parts store that can certainly say that I'm getting a replacement for the Valeo alternator?

Ive been reading other posts but haven't seen an answer to the compatibility question. Thanks.

Oh and FYI the part is in the $190 range at all the stores.
