hi all ,,,   i have a nos timing chain that was purchased for a y block  but is clearly wrong.  it is new old stock  but i think  it may have been in the wrong box. D and B silent chains is the brand on the box and number     C 492 .  the actual chain which is a link job has no numbers at all just USA   m ade on the links .   is there anyway that i can work out what it may fit??  is it for a similar Ford product??  any clues would help. no pics yet.  maximum width across the links is approx 13/16 s .  1/2 inch from rivet head to rivet head. overall length when rolled out is 24 inches.
