What I do to test for cross compatibility is search for the part on the newer model and see if real oem shows that part on the older model.

(Or when real oem doesn't differentiate, just look for the year range).

The issue you'll have other than coding is: does the newer model have the wiring harness just in case it might have air springs. (look for that harness in the older car and look for empty connectors in the new one).

I loved having air spring since I would often carry 1000# of tools and even tow a trailer at the same time. I'm definitely in approval of the project.
