2000 Chrysler Cirrus Alternator Adjustment bolt

The adjustment bolt for my cirrus came loose and fell off somehow, i was wondering if a regular bolt will work or where to find the adjustment bolt. Also the blet that was on the car now seems to be to large by about two inches, can i just buy a smaller one?

Goodyear belt #4060560 is made exactly for the crysler/dodge 2.5L engine. As for the 2.4L, Dayco part DY5060530 is out there. Those should fit exactly. And as for the adjustment bolt, just go to a dealer and grab it. The premium you pay will ensure no screw ups.
