I'm taking my 88 firebird 305 tpi and putting it in a 85 iroc that has a 305 tpi i had to replace everything from engine to wiring and disconnected the two peices on the top of the steering colum the ignition switch and dimmer switch and cant figure out how to get them back on the steering column i've looked in my chilton book and it dosent show me anything any ideas please respond. Well after searching through the car floor i found the metal peice that i was missing to figure out the problem
