ABS shock on a 3CV question

[joebloggs]

I found and bought a used Hagon shock to replace the stock worn out item. The shock came off a abs bike so, from what I understand, the clevis on the lower mount is wider than the 3CV's
The shocks in the post and will be a few days before it arrives, does anyone know the length of the bolt required, and length of the shoulder. I know I could order one from Yamaha but to save time on measuring I thought I'd ask on here.
Thanks
Joe
