Swapping heater core with evaporator

[MN67C20]

Hi all,
I am wondering if it is possible to swap the heater core out and install a AC evaporator. I don't plan on needing a heater but want AC and am looking to find out the easiest way to add ac with out spending an arm and leg. I was looking at grabbing all the AC parts off a newer chevy truck and retrofitting them into my truck. Please let me know if I am on the track or missing the whole idea.

Central MN and no heater? anyways the hole for the heater core is way too small for the evap core. Look into an aftermarket AC unit

I think someone on here did this exact swap.Showed in detail how to modify the firewall to except the factory A/C stuff. Might try a search.

I have done the swap with stock components and it wasn't that hard.
I am also tinkering with the Idea of installing an evaporator into the heater core opening as I think you are trying to do.
I just haven't come up with a good idea for the vents.
My 2000 Toyota Echo evaporator is almost the right size but a few inches too deep. Also not sure how to mount it in the box yet. Kind of a hair brain scheme as I was just standing there wondering if I should just get rid of all this junk.
I already have all this stuff left over from replacing everything in my wife's beater.
Her compressor gave up due to a impeller breaking. So I thought Hey why not stick it all in my Cheap build Blazer "No Daggum Money" build and boom Ice Cold air for almost nothing.

Thanks guys for the replies. I was just thinking is all I need is a way to get cold air moving in the truck and swapping out the heater core for an evaporator looks to be the easiest way. I thought about running the ac pump on a thermal switch and use the standard heater controls for the fan. The other idea that I have been thinking about is using a self contained under dash unit out of a mustang or focus. Any thoughts?

I think an underdash unit is the easiest way to go. You can get the unit itself new fr around $100 on ebay.

Does anyone know what will fit the best under the dash? Make, model would help greatly. Thanks for the imput.
