Split personality, I fake being smart
Exhaust kit is a decent price. Diameter is a bit big but will work on 360. You may need a larger secondary main jet, 117.5~122.5. Don't know what happened to sync screw spring, was OK when fitted. I still don't have definitive angles for operating arms, you may need a small round file to modify the opening depth as I found they do not always line up even close, around 1mm or more different length. The pictures Trek posted above show arms pretty much parallel. I don't know if the production variations are causing problem? Be very careful if you try and bend arms, the shafts are brass and can easily break. I support the flat plate with a small channel lock when adjusting angles
