In attachment picture of 4 bolts + nuts for the fixation of the shock tower braces to the cowl.
I hope that I am explaining it correctly?
In the Osborne assembly manual I couldn't find a description for that hardware and couldn't find an answer here in the search function?
Any help would be appreciated for confirming the correct finish for the bolt and the nut.
Thanks in advance for your time and effort.
Kind regards,
Jeroen
