Look at the application notes on the various brands.
Raybestos lists the 769 as fitting 90-06 and the 538 as fitting 90-00.
Other companies list them as fitting 90-06.
I do know there was a friction change in 00 where they removed a strip of lining down the middle but I never see that in the aftermarket. Maybe they just reduced the friction effectiveness on the later stuff.
I do know I've had a few brake companies call me and ask if I know why Jeep did what they did and I have no good answer that I can prove.
