The colour scheme was inspired by a British Railways 109 I saw on the London To Brighton run, it's known in trainspotting circles as “Blood and Custard”:
It looks like the paint codes are:
From EMF Rod Ends (Canada) - Heim Joint, Small, 3/4-16 Thread RH Thread / Ball 1.625 x 3/4
Sleeved ends are M12 fine bolts.
Drop arm bolt is 3/4“ UNF x 5”.
