We all know how much of a pita these suckers are (it has been bypassed for 3 years now after it blew racing ), just need some input on which way is "easiest". The a/c on the 5.0 went warm at the beginning of the summer and since it hasnt been charged in like 5 years its obviously gone and its time for a r-134 conversion. I dont really want to do the a/c at this time though. Is it that much easier to disconnect the a/c and pull both boxes out or should I just do the cheater way of unbolting the dryer and working on the heater box under the dash?

well, my core sprung a leak last week.
I'm changing it on friday. I'm going to be doing the Dash method. Taking it out, or at least partially, and removing the entire
box. Seems kind of easier to me since you can work on it on the bench in decent light.

I've never taken out the dash in this body style before so it should be somewhat interesting.
I've heard time quotes on these cores anywhere between 3.8 - 12 hours.

Take your time and remove the dash and console.
I have done several of these and there is no easy way Tim.

I just finished mine. Took me 8 hours.
But I like to work slow.
IT was a pain in the ass getting the bottom HVAC box screw in and getting everything lined up.

i have done a few stangs and birds and even a towncar or 2,with ac the best way i've found is the long and hard way,plan on a good day of changing it out! p.s.if i was you i would pull the heater box all the way out and do the blower motor and the evaporator also while your allready there!

If you are going to yank the dash out, and disconnect the A/C lines....even though the A/C might be dry, If you plan on using it again, you need to somehow seal off the lines going up to the front, as the dryer will absorb water out of the air....or, just replace the dryer when you get the A/C fixed...
