Got the condenser in today...So pretty

Went with Behr over Nissens because I got the hookup on a brand new Behr for the same price as the Nissens so since MB used Behr as the OE, I went with Behr. Says made in Thailand..
I am going to TRY and see if I can simply bend my current A/C to fit instead of paying for a new hose simply for location. It may work since I can bend the metal. Worst case I have to get the new hose from the junkyard. No biggie. Will report back if it works.
Next up is to evacuate system, remove radiator, attach dual fan assembly, install everything, add oil and recharge.
Now -- I have had nothing but large pressure before with r134a. Should I instead charge by low side and by measuring the evaporator temperature? Is that a better way than simply doing 80%?
The system wouldn't even ACCEPT 80% of the weight before.
