So I just got a 88 samurai for my birthday and I bought it broken. It runs perfect but it doesnt move. The gear shift and the transfer case are not stuck but the thing under the transfer case only spins in neutral on the transfer case not in 4l, 4h, etc. I'm very new to working on cars I don't know what's wrong. The guy said it needs a new clutch so I bought one and its on the way. Once it gets here I'm going to try to install it from underneath? If you know what the problem is please tell me or if you know it is the clutch let me know. Thank you and if u have any tips about replacing the clutch it would be greatly appreciated
