Ok not sure about the t-top and dash connection. All plastic around the windshield is removed and everything else, other that cannot get the steering wheel to lower?. My email address is in my profile for anyone to send i nfo. Will be looking at it again tomorrow morning and give an update.I feel the clips at the back of the dash are rusted and holding it on. Question when I open up the heater core box can I just replace that or am I getting involved with the ac evaporator also since I have air?, or can I just remove the core and replace and back together. Thanks

Ok the dash is off! the two clips were hanging up and I removed the clips and it fell right out!

Still the question why the steering column will not lower I must still be missing a bracket?

And second can I remove the heater core withlut messing up the ac evaporator since I have AC? are theynot co-located where I need to attend to both if I open up the door?

Also are the bolts removed from the inside or the firewall/wheel well, have not looked close at it yet but I am assuming the bolts.nuts remove from the firewall and then slide the box out from inside.

Ok still decideing wheter to do the core, it looks good now but?????????????????????

later. BB78

As I remember mine did not lower a lot but did come down some. I will look up the drawing on the wheel and send it along to you with the others. By the way I just checked your profile and your email is still hidden even though you said you set it to show.

I will sent it to the one that you PM's me with.

The steering wheel column can be lowered and removed after you have removed:

1. The rag joint in the engine compartment.

2. The two nuts and bolts at the firewall.

3. The two nuts under the dash gages.

4. Electrical connections.

Yes, your upper dash pad looks beat, but the stuff below still looks pretty good.

I replaced my heater core in my '73 with A/C, and it didn't have anything to do with the A/C Evaporator. I also used a hand operated vacuum pump(Mity-Vac) to check all the heater controls and found two leakers. The whole heater assembly looks complicated, but once you get it off and on the bench, it all makes sense. Take lots of digital photos before disassembly!

Hi Mark, judging from your pics I can't see any reason why the column shouldn't drop down 2-3". That's the way I remember it.

Now that you're this far, without a doubt replace the heater core! They're not that expensive and I would hate to see you have to tear it out again! The cores may look good but you can't see the inside. When the core lets loose it may damage the passenger's side carpet (and try to explain to your wife or girlfriend "It's just antifreeze, hun, don't worry about it!"). You've went this far, don't skiimp now!

And do not forget to change all of the light bulbs. Go to this site and you can get all that are required for less than $5. Any place else will cost you $20 or more.

http://www.memotronics.com

I will send you a pdf on my research on dash lights. I purchased all of mine from this guy took only about a week to get them.

Adam I sure wish we could attach a pdf to something either a PM or something.

What a bummer I just check the web site and he is closed up for vacation until the 14 August.

I really do not want to but I have 17 ANSI Bulb Number 168 Made by CEC. that I purchase a year ago from him for $.23 each.

But be aware that he now advertise them for $1.99 a box of 10. It looks like the price dropped. If you want mine you got to pay what I paid for them. Anyway that is the deal plus first class postage. PM me with your address if you are interested.

Now that the heater assembly is out, take some time and study all the levers and actuators. Clean and lubricate everything that moves. On mine, I found one of the actuator rods was nearly worn completely thru and ready to break off. Time well spent.

Ok the new heater core is in!!!!!!!!!!!!!!! Not that bad but the duct work back together was tight.

Now I started it up to check leaks and it looks good but cannot get the blower switch to work.

It was not working before I took the dash off but thought with everything out I coule d find the issue but I cannot. It had worked in the past.

The fuse looks good.

The relay has pwoer to it and its clicking?

There is power to the 4 positions switch but has 5 wires so how do I test that it has power where it needs to be.

So could it be the blower itself?

Stuck on this for now, checking the wiring diagram if anone has a imput I will take it, in troubleshooting?
