I'm looking for some data and availability information regarding bypass valve springs part number 713-36 and 713-39.
According to the Palmer books the 713-36 was used up until early production 39' while mid/late year production a new spring 713-39 was used.
Spring 713-36 is advertised @ 1.3437" in length
Spring 713-39 is advertised @ 1.7812" in length
For reasons unknown to myself, these part numbers are not found in the supersedes chart shown below...

Does anyone know of an superseded part number?
Does anyone know of availability on either one of these part numbers?
None of the aftermarket companies address either of these numbers to my knowledge.
Would anyone know the wire diameter and O.D of these springs?
Thank you,
Duke
