You'll need a dryer. You should ad a water cut off valve even if simply a hand operated ball gate valve from hardware store. Then blocking that small portion of the cooling system along with the added a/c condenser leads to needing a fan shroud. The added drive belt may require a different crank pulley, a tension idler pulley.
Wouldn't it be great if the under dash unit was all in one, like a household window unit? That's not the case.
I mentioned before that I have the condenser. I'll go ahead a mention a new dryer here. I may have a mounting bracket for it. Not sure what else I'll find here. Price suggested earlier was for the under dash unit alone.
