How do you swap the a/c evaporator?

Daminc and I discussed it lightly a while back. What's the best way to swap out the evaporator?Mine has been open to the elements for about three years.I have a new one in the box,and figured I may as well swap it when I start installing the other a/c components.

It's kind of like doing a heater core, only worse.

I know I have to pull the dash and get the casing out,bit how does the evaporator come out of the casing? Jerry and I thought you have to cut it out.....if so,how would one re-seal it,or is there another way?

I replaced my son's at the same time as the heater core for the sake of already being there with the case on the bench. I followed the service manual procedure and used strip caulk after cutting the case on the lines in the case. I can type it out if you want, there's also screws to be installed if I can transfer the pictures. Let me know

there has to be another way to get the box open than to cut it.  getting past the sealer is going to be the biggest pain..

this is the only way in Vinnie.... cut between the lines, and reseal it using a seam sealer.
I'll send you the instructions tonight.

BTW.... only the 87-88 boxes have to be cut. the earlier ones screw together apparently. (according to the manual)

EDIT sorry for the mis-info........... 83-84 boxes are the only ones that unclip, or unbolt

Yep,I've had to change heater cores a few times....that's why I am really fast at it now (I really am).It's too bad that I had to go through  a lot of agony to get that good.LOL.Oh well,I gotta do what I gotta do. Thanks Jerry.

That is so stupid.  Why would they cram something like that in there and then make you have to cut the stupid heater box to get it out?  I guess because it was cheaper to build it that way? 

I hope you can get it taken care of, Vinnie.  I paid a mechanic to replace the one in my car when I was having the heater core done. I figured as long as they were in there, why not?  Did not know how involved it was.
