A/C evaporator

71 F100 with factory air - big job replacing the evaporator? Lines?

I did a search but didn't find any info on it.

Shouldn't be too hard, depending on your experience.
A high level outline.
Drop the unit from under the dash.
Pull forward to get as much room as you can.
Then disconnect the lines to the evap.
You will need some big (large) size wrenches. Like 3/4 to 15/16. Use two wrenches to hold when you are removing or installing the lines. One to turn, the other to keep the evap lines from twisting. You can easily break the pipe/fittings if you don't. They are fragile.
You will have some wires to disconnect then you should be able to take the whole unit to the bench where you can disassemble the vents to get the evap out.

As far as I can tell there are only two bolts... one on each end... holding the unit. Is that correct? Don't want to pull on it too much until I find out for sure.

The other possibility seems to be removing all of the small bolts and splitting the housing.

Mine only has 2 bolts, one each end of the unit.
You will eventually take the haves apart but it's easier to do
on your workbench after you remove the hoses and wires.
