Parts are expected to be available on 9/1/89. Until then, normal part orders will not be accepted by GMSPO. Only verifiable emergency VIP orders will
be accepted. SPO will make every effort to obtain parts. All parts will be placed on 400 control to waive VIP surcharges. However, the part will be
shipped premium transportation at dealer's expense. All other order types will be cancelled as incorrectly ordered while the 400 control is in place.
