evaporator core leak

ac works fine when charged, but the evaporator core is leaking heavily. was thinking about replaceing it and wondered if anyone has tackled this job before.PLEASE HELP i need my gmark to blow constant cold air again!!

THanks

Haven't done the evaporator myself but the condenser was actually pretty easy. One thing to remember since you are opening the system you should also replace the Orifice Tube and Receiver Drier/Accumulator. Looks like if you hit rockauto.com you could be under 70.00 for all the parts.
