Interior Firewall Assembly Order

[JimKueneman]

I remember when I disassembled the interior getting the steering column flange that mounts the column to the firewall past everything was a bit of a chore. This is an AC car so the heater box is large (not sure if that has any bearing on difficulty)

For those that have done all this before what is the best order reassemble the interior firewall items with the least amount of effort? The brake assembly is installed, left to install are:

Gas Peddle, Steering Column, AC/Heater Box, Dash.

Based on what I recall there are a lot of reasons to leave the steering column till last (because of the dash) but that means the AC box would be installed (or would it need to be)...

Just trying to not have to assemble/disassemble things 3 times like some of the previous items I have installed!
