67 A/C heater box rebuild and install help

Hey Red, the only reason for wanting to remove it is to replace all the insulation in behind the evap coil. We have the kit from DMT. Im thinking I will just leave it like you said,but I will take the unit to an ac shop to have it tested and hope it comes back good.

Thanks!

Can you see the other end of the tube on the other side of the vaporator?
Like I said they are normally attached with some sort of clip to prevent metal to metal wear. If it has a bulb on the end the rubber grommett in the case might need to come out with first.
