I got a couple of messages on the spring mount so here it is a 5/16 heim joint with a pair of jam nuts to set preload I added a small safety retention on the pedal itself so the spring never comes off accidentally. The mount itself is a 3/16 chassis tab with a bronze bushing and a cage gusset. This was an idea I came up with to make the unit serviceable for removal if needed and adjustable as well (got the idea off a tractor actually)
