Yes, powered OEM door and rear hatch options not available in '98.

Theoretically, it could be possible to retrofit the hardware from later years into a '98. It would require extensive mechanical fabrication (creating new hardware and modifying existing structure), as well as custom electronics (to handle new remote channels, etc.). This sort of thing is usually reserved for the custom/hot rod crowd who enjoy the challenge, and have lots of time and money to invest.

Let's put it this way: This project would likely cost more than the van is worth, between hardware and labor. And imagine that, even if you found a way to do it, if the van were in an accident, you'd automatically lose that investment (your insurance company wouldn't be interested in covering such expensive modifications unless handled on a separate 'agreed value' rider).

I agree with bhorn: Start looking for later model that already has the options you want.
