I have done this several times. I will try to walk you thru it. Unhook the battery, remove all the wiring from behind the cluster, then remove the cluster(3 screws in front, 2 nuts behind, speedo cable). Remove steering wheel, dis-connect turn signal switch, remove column floor pieces, remove colmn to dash bracket, remove column. Dis-connect heater cables, vent cable, & wiper control cable. Remove ign. & h.l. Switches. Disconnect all remaining dash wiring. Remove inside windshield trim. The dash is now ready to remove: 2 bolts on either side at the bottom, all small bolts along top(under ws trim). Once the dash is out, it is very easy to remove everything else from behind. If you have any further questions, ask. Good luck.
