I just installed Moss's 3/8 inch belt kit - it has the same length belt as the original, however the pully's are a smaller diameter - to get proper belt adjustment I am at the limit of adjustability - is there anyone out there that runs a shorter belt - if so what the number? midnight

The part number on the outside of the belt is usually a reference to the size of the belt...usually in 10mm increments. If you need smaller, just go down one step. Be aware that the same manufacturer will have several styles, so try to find the same style (i.e. grooved, extra thick) to get a direct comparison.

The kit should have come with a belt, mine did the number on the belt in the kit is QBA975, I ordered a spare it is from FAI Auto Parts Drive belt 10AV0975.
