KTM 640 Adventure Roadbook holder

Can someone tell me the length of the original hex connectors?

Knocked up my own bespoke thing that now mounts a zumo 550 and a montana side by side have never seen an original in the flesh but if I can help someway with measurements etc-no problem.

I've finally managed to find a new and genuine holder, but I need the spacers. As the studs are 12mm long, and the bolts are 12mm long, I know they're at least 25mm, but would like to know the length of the original ones.

I used a bit of turned alloy bar drilled and tapped both ends to suit fixings m6? KTM stud and m8 for my bracket lug to create a spacer post then cross drilled through in the middle of the length maybe 3.5mm diameter to allow me to nip it up on the original ktm stud probably the length is about 30mm dont know if thats any help.
