[LT65]

Just checked my car the mc a reco unit is not stamped but the leaky one I originally sourced from a wrecked panelvan is stamped 3.1 on the end where the front brake ports are. However I did notice the rear brake port plugs are a different anodised colour the panelvan mc is green and the one in the car which I am assuming is a seden mc due to braking performance is red. Maybe coincidence can't really know.Maybe a bit more of the puzzle.
