I have a new heater core and hoses for my '78 C3 and was wondering how long should this take to fix?

Should take you a few hours if you are handy in the garage.

Anyone have a cheater sheet on how to install with some tips? :)

Hello
First remove the trim panel under the steering column then loosin the two bolt holding the steering column up and lower the column, next remove speedo/tack cluster then the radio and center gauge cluster then the glove box, A-pillar mouldings, next remove the dash speaker and defroster grill then the dash assembly. At this point you can see the heater box, there are 4 bolt holding it to the firewall, inside the car two on the bottom of the box and one in the upper right. Under the hood there will be a 1/4 stud with a nut on it holding the a/c box to the firewall. Its just behind the fan speed rheostat in the air box, remove this nut and the heater hoses. At this point there are still a few small things to unhook that you will see, but after that you can now remove the heater box from the car. Nothing to it!
