1997 only parts???

I have a 1997 XJ, 4.0, AW-4/231.

I've learned that the TCU and Transmission won't interchange with anything but another '97. Are there any other "1997 only" parts I should look for when I hit the junkyards?

TIA

IIRC the electrical is all different on the 97. So...harnesses?

Gauge cluster, TCU & ECU. All have to speak the same "buss" language.

Door hinges are old style but strikers / latches are the new style.

IIRC.... the heat & A/C controls are different (97 uses a cable for hot/cold blend adjustment.
