Please see photos attached. Original post appears to be lost. Length is 28 inches, and width is 9/16 inches. Imprint is 27 3 LN CALDWELL. Looks like this is your 2730 part... Please confirm

"2730" is just a code that tells us how strong the spring is. The stamp has no bearing on product identification otherwise. That said, yours looks like our S350-28. Carefully look it over and tell me if this is a match.
