HeyCharger Posted August 31, 2006 Share Posted August 31, 2006 Hi Guys.Recently, someone said look for the number that is stamped UNDER a mount on the front right hand side of the engine.Sure enough, when the grime was wiped away was 1431 H 12 149.Whoever it was, suggested that this number is significant.As I said, this is not the engine number. My engine number is END673P-673-H 63.Any thoughts? Thanks. Rod.
