Leaf Spring P/N Question

Looking for the correct original part numbers for leaf springs on 69 XR7 351 A/C car.
None of the reference books I have list these part numbers. Thank you.

There are a few threads already going discussing this

Be aware that part numbers and engineering numbers (the ones stamped on the spring themselves) are two different things and are different. A 69 Mercury Master Parts Catalog should list both numbers but not sure how much access there is for these catalogs for Cougars/Mercurys. For Fords they and later versions of the catalog are everywhere.

BTW you didn’t list if your car was a coupe of a convertible which often makes a difference in this wort of thing. Guess there are at least 4-6 different rear springs that were used that year on 351 Cougars based on the build sheets I pulled up

Thanks for the info. The car is a Coupe.
