I'm going out on a wing here, but I'm guessing that Yes, the same model year trooper CV will fit the VX.

In 97 I believe, Isuzu widened the front axle, making the shafts longer. Just stick to the same model year trooper part and you *should* be ok. One way to find out would be to find a part number for them both and see if they are one in the same.

DISCLAIMER: I haven't actually replaced the CV's on the VX yet so I cannot say for sure.
