Suzuki 2 Strokes

I need someone to verify the diameter and overall length (less knob end) of the GT550 rear axle. I need to dig through my spares to see if I have one to help a fellow board member in need. According to my parts manual they were all the same 73-77. The only thing I have to compare it to is on the bike and I have no plans of taking it apart Thanks.

The swingarm is the same width as a GT750 but the axle diameter appears to be 2mm smaller

I'll have a look when I get home. Currently working in Ireland.
