Im in a bind, i have the mazdaracing street pulleys (anodized red that says MR on them) . I Lost the paper that came with them to tell me the new belt sizes i need to run for the power steering. I neeeeed power steerin. Maybe the AC too.

 

Just take a peice of string, run it around all your pully's. And measure the string. Then go to any parts store and ask for a belt that length. Make sure to leave some room to beable to slip of over the pully's. Your tensioner will take up the slack.
