I'd look at the frame rails near where the engine mounts are and underneath the car. If they have holes, forget it. If not and you are not trading more than one arm, go for it. The t-tops and wheels are worth more than $100. The interior parts are not cheap, but available. I can't remember if that year had the digital gages or not. If they are digital and don't work, they will be hard to replace.
Where in ID are you? You can pm me if the car is not too far away I may be able to take a look.
