I have never heard of a 97 with AD injectors. I believe those started with the late 99 or 2000 model year. The 97 California emissions trucks had AB injectors while the federal trucks had AAs. That said, the solenoids are interchangeable.

Also AD are 140cc split shot.
Either way a custom chip can be programmed to make either single shot aa or split shot ad work but you need one or the other as a whole set.
Yes the solenoids are all the same.
