You can bend the mounting brackets on the accumulator forward to allow the extra clearance needed to get to the heater box cover screws.
It can be done without discharging the AC system,which is a bonus.
Agreed, I have done this twice without discharging the A/C. First time took me 9 hours, second took me about 6 and this is working by myself.
