2002 was a difficult year

Appreciate this is a long shot, but does anyone know whether an alloy swing arm from a 2002 620 S I.E. will fit a 750 I.E.? Part numbers are 370.1.028.1B for the 620 and 370.1.021.1C for the 750 - this information probably doesn't help much. The 620 part no. seems to be unique to 2002, from 2003 on it ended in 1C.

I'm guessing that your 750ie is around 2002 also? If it has the connecting rod to the suspension rocker as opposed to a Hoop then I think the swinging arms will interchange no problem. The other thing would be the rear axle sizes, but I think they would be common to all 2002 models? 25mm?

The 1C suffix seems to denote steel and 1B would be alloy? I can't see the critical dimensions being different.

Hopefully someone can confirm my uninformed assumptions.
