Hello Gents

I need to replace my swingarm which is bent. The bike is a 2004 Gen 1 Factory. Other than colour, is there any difference between the various gen1 Tuono swingarms and the various gen1 RSV Mille swingarms - ie can I buy a swingarm from a 2002 RSV Mille and fit it to my T? They obviously look the same but I'm wondering if dimensions are all the same.

Many Thanks
