You can use a '91-'04 throttle body, but if it's a '95.5+ throttle body you will have to cap the vacuum port at the base of the throttle body. No big deal.
My '95 came with the '95.5+ throttle body with the vacuum port capped from the factory.
BTW I sell 62mm throttle bodies for $85 + a refundable core charge. Much larger, more power, and quicker throttle response than any 4.0L throttle body. Removing the stock taper beneath the throttle plate gets air past the throttle plate a lot sooner.
