There have been a lot of threads regarding these belts in this and other forums They are never based on technical details that is why I am working on an overview of the belts used on different Ferrari's I am still looking for the following information regarding the timing belt (132843) of a 348 : Number of teeth + Width(mm) + numbers on the belt (132843 among others) This is the only information that is missing at the moment Will post an overview here when it is complete
The details are usually stamped on the belt. I havent got a new belt laying to help you with the details mate. But there have been a few blokes here that have done their major services recently that could probably help you out with what you need.
