Hi Guys.

I think I have a Fiat 500 R gearbox. The engine was a 600 that came with the car and the box should be a synchro...which it is. First gear is dying so needs replacing but I read there's a difference between a standard and an R.

Pictures below of the numbers on the side of the casing if that helps id it?

Many thanks if you can helpI

The R had a 600 engine and a non synchro box as standard, so if yours is synchro it will be from a 126 with 500 driveshafts
