we have an 85 grand wagoneer, with a cracked 229 transfer case. also have a 79ish wagoneer, but not sure what transfer case is in it. will the two interchange? didn't know what the options were in the wagoneers, i'm trying to help out a friend who has cancer. just need to get it where he can drive it again. started out needing a starter and then found the cracks in the case.
