Would anyone be able to provide Land Rover part numbers for Leaf Springs?

I need a complete set for 1967 NADA with 6 cylinder engine. My 2 parts manuals show different numbers, one says number fits "all models" but I don't believe it, I think they are for 4 cylinder engines.

The NADA parts manual doesn't have Leaf Springs listed.

I'm trying to confirm the part numbers, I understand all four (front left, front right, rear left, rear right) all have different numbers.

Any help would be appreciated.
