Parts are expected to be available on 4/6/92. In case of limited inventory, parts will be placed on 400 control to waive V.I.P. surcharges. Only verifiable
emergency V.I.P. orders will be accepted. GMSPO will make every effort to obtain parts. However, the part will be shipped premium transportation at
dealer's expense and all other order types will be placed on backorder until the 400 control is removed.
