Color coding NOS SHP parts

[al8apex]

not exactly

a hi-po axle shaft has purple paint on it, the lo-po (is that a word) ones had a different color (can't remember, only remembered the "good" stuff colors), nothing to do with what shift, it was application based, not shift or employee

Different model of part, low po and high po. What I said and what the guy above me said.

Not all marks are for models, some are for shift and some are a check mark meaning the part passed a certification point.
