help removing instr. cluster

Hey guys been trying to figure out how to get the instrument cluster out to change the wipersand make them work again (seized up) and I disconnected the speedo line but the restof the wires ddon't seem to have enough slack to give me access to the back of the cluster... so if there are any A body guys near central illinois or have any photos or insight to help please do... plus I would pay someone to come redo it for me LOL I'm having a headache with this one, being 6,1 330lbs makes Iit hard to play under the dash:violent1:
