Please open attachment containing the 337 and data reference used to modify my aircraft back in 1971. You can use the 337 and letter from piper along with the paperwork from kit 757-004 and piper drawing 69046 to modify your aircraft.
Mine is s/n 28-10333 so it was the 33rd off the line. It appears to have the original heated pitot and Aircraft Logbook confirms.Yours is a later s/n . This is the 72nd one built, and pitot heat was not an option for this s/n . The IPC and piper tech rep both confirm this.
https://www.faa.gov/documentLibrary/media/Order/Order_8300.16A.pdfBottom line is ,the FAA burdens the installing technician with determining major versus minor and the owner makes the ultimate decision of airworthy. The modification may never cause an issue and in the case of the heated pitot tube, would enhance the safety of the aircraft. The installing technician needs to make him/her self aware of any data that can be acquired to safely install the modification and is done with at least acceptable and/or approved methods.
