Pt Number 71.3013 Triumph Twin 1973-....AN lists this as 5/16UNC x 1/4 UNF stepped stud.
LP Wms lists same part number but 3/8UNC x 5/16 UNF cyl base stud.
Anybody know which it is?

I haven't checked the part number but if the part in question is aone of the outer four stepped cylinder base studs, the LPW version is correct.

Final word: AN order arrived but has the wrong tag on that part number. In my hand just are four 3/8 UNC x 5/16 UNF studs.
71.3013 is indeed the correct number. Steel, zinc plated.
