Hi Patrick
This is from the build instructions,that i have from 1994
They say sidestays: 6120mm +GYS 131 adjuster(i think that is there adjuster) 3mm 1x19 wire
Forestay: 5570mm +GYS 133 adjuster
I know when i made mine i measured from the bearings surface of both thimbles.I didn't use there adjusters
Hope this helps
