I just used a bolt that has similar dimensions and can fit through the center stand.
I think it was a $6 bolt from Fastenal, industrial hardware store.

 

If I remember correctly it is 10mm

 

Well I got this stand on ebay for about 50 euro, will have a go at fitting it what I get a chance, I might need an extra set of hands, there was no pin with it but when I looked again at the assembly on the bike there was already a pin there bolted on, happy days.

 

Hey just to update, the stand was cleaned up and fitted, handy job but it is contacting the chain when it's on the side stand. Looking at other threads seems the stopper that goes with the stock exhaust would normally prevent this. Just looking at pics from 'A' is there a little mod to he stand? perhaps the stand I have is slightly differen, any help appreciated.

 

II think you are correct my F3 and F4 has the stop which was on the exhaust.
If you look closely at 'A's picture there appears to be a small rubber piece near the pivot point on the L/H side which I assume does what the bump stop on the exhaust would do by resting on the bottom of the shock support
Maybe!!
You could possibly fashion something similar?

 

Looks that way, guess I'll have to stick it on the project list and fasion some sort of bracket with a stop, should be straight forward enough, cheers.
