Not offhand, it's a bit busy at work today. Use the 'search' function for 'dash removal', 'dash', etc and see if you can find something that might help.

When you go to remove the dash your going to have to remove the e-brake handle and also the dash first tilts rearwards then up and out!! I just helped Rcars2 with his heater core!!

To disable the airbag first disconnect the battery, then behind the dash next to were you shoulda removed the glove box there is the yellow wiring for the airbag disconnect it there as well. Just to make sure you did a few things did you take out everything in the center of the dash and also glove box plus gauge cluser, there is several hidden bolts you need to remove behind those locations plus on top of the dash were the vents are you need to pull those long vents to get to i think its 4-6 bolts.

Did you get the 2 bolts (10mm or 13mm) in the upper kick panels on both sides? They're really hard to see.
I have never taken the dash all the way out of the vehicle. I used a bungee cord from the handle on the dash to the handle above the passenger door to lift the dash for clearance.
I also took out the steering column bolts and let the steering wheel rest on the drivers' seat.

The passenger air bag will come up with the dash.
Any bolts from the engine compartment should only be holding the heater box, which comes out later, if I recall...it's been a few years since I've done this myself.
If you try to lift the dash is there an area that still feels secured? Did you read my post from a couple of years ago?

Ok, next question.... on your RPO code it should tell you what a/c system you have. Is it C42 or C60?

Wow, im missing threads left and right here. When i get home tonight i will take a pic of my engine bay and show ya the 2 bolt and one nut locations that you need to remove to get the heater box away. Its hard to explain but you need to remove the nut off the stud that comes through the center of the firewall, then there is one bolt thats attached to the heater box in the engine bay itself about on the passenger side, and then there is the SOB thats in the engine side of the heater box. To get to the last one look at the engine side heater box for an electrical plug on top. It will have a rectangle around it marked cut here for service, take a utility knife and cut that out (its only rubber) and you will find a few bolts holding in whats call the resistor. Remove the resistor and look inside and you will see a bolt in there more towards the passenger side about half way down, that little bugger is it. Remove it and the whole inner heater box will come loose.

Edit: Here is the link to the pictures. Link

I don't believe there is any cutting required with the manual a/c, only on the auto a/c.
