Ign switch has gotten stiff and won't spring back when starting. Any ideas what could cause that?

My recommend to the Edelbrock system. I too plan on that system vs Holley Sniper. ROBBO

Hi Doug, I just saw your 3 month old post so I assume its no longer relevant but anyway Im no expert but would agree with you that a single feed line from the tank is all you ever need. The return line is unnecessary in my opinion and the charcoal can you mentioned is mainly part of the anti gas fumes device of the day. If you want to keep it original then retain the charcoal can and all the lines as they were meant to be. ROBBO

OK what a PITA job this is but doable. Didn't have to remove inner fender well or cut a hole. The lower outboard nut behind the fender well is reachable and was removed without too much difficulty along with the other 3 nuts on the firewall which hold the heater box on. Of course most of the air ducts need to be removed after the dashpad is off. The defroster duct can remain in place.To get the ducts out you will find there are some other small things to take loose. Mind the wires and vac lines. Remove the pass side kick panel too and the lower dash air vent assembly it has 3 hard to see fastener nuts. Now the heater box can be pulled away from the firewall and laid down on the floor. Remove 8 screws from the metal back plate of the heater box and also 3 screws on the top which hold the damper mechanism in place. Be sure to mark the location of this mechanism for easy reassembly. Lift the metal plate up from the heater box and pull out the core. Careful when pulling the metal plate away from the box as it is made of fiberglass and can be damaged. Don't ask how I know. Reassembly in reverse order.

thanks Rob. I did read that a 1" hole can be cut in the fender well to access the lower fastener to the heater with a socket wrench. It all makes sense now. Remove dash pad to access fasteners on the inside and remove those on the firewall engine side. Disconnect air ducts from heater box. Remove passenger kick panel and drop heater box. Easy peasy we shall soon see.

oh Rob say it aint so. The inner fender well. I am assuming the ac evap assembly comes off too? Does the heat core come out the front then?

Looks like I need to replace the heater core in a 72 with ac. Anybody have any suggestions. Does the dash need to come out? Any tips appreciated.
