I know it's a 69 pontiac built Nov 15 1968, go figure. Now... under the 0296692 code is a mess. This must have been stamped on 4:30 friday. It has a large 0 or O first then a large 7 (by large I mean bigger than the #'s above) with a jagged line crossing through diagnally then a S. The S is the only correct size stamp from what pictures I seen. These are not in a straight line but stair stepped about 1/8". If you guys can't visualize this I could try to send a pic. but haven't done it before. Jeff
