Metco 03/04 Alt Pulley on GT Alt

[WhiteFaleen2001]

Does anyone know if a Metco 03/04 alternator pulley will work on a GT alternator?

I purchased a 15% OD crank pulley but now am concerned with over spinning my alternator. Seems like a 3.2 or 3.5 metco pulley would be the solution but I was curious if you guys had any thoughts.

Thanks!

I tried using a Metco pulley on my 01 alternator and it stuck out too far. If I had the spacer lip machined it would've worked.

Well crap. Now I am not sure what my options are
