Can anyone tell me which years the rear axle will fit in an 87 without mods? Our daughter moved 300 miles away to school and the rear axle bearing went out. Mechanics quoting $750, which she doesn't have and we don't... so plan to find an axle, pull the bearings and rebuild, then take to her and install. We know the 85 is different, but not sure when they changed and for how long they will interchange. Thanks!
