both for 131/132/argenta gearbox as declared, they're for diferent years, both for 5speed box. after 1978 or 79 fiat started making gearboxes with smaller teeth because they make less noise. parts are not interchangable for obvious reasons. transmission ratios are pretty much the same. never actually bothered to count the teeth on reverse gear but safe bet would be that one with 17teeth would be for older car, although who is to guarantee that gearbox wasn't swapped over the years?
