GM Protection Plan old parts

[partsguy99]

Anybody know where in GM P&P or somewhere else the policy for parts replaced under
GMPP? Are they to be handled like a normal 3-36, 4-50 warranty part replacement (i.e. tagged and returned to
the Parts Dept.)

no need to hold parts for GMPP but I still have the techs tag them like factory warranty parts just to avoid confusion.

we don't hold GMPP parts. Techs toss them
