And here is the semi-final result. I installed an old receiver/dryer so as not to ruin the new Delco unit I purchased. Once you open the block offs on a new receiver/dryer you have 15 minutes to get it installed and evacuated or the desicant material soaks up all the moisture and is ruined. So I will vacuum test the system in a week or two to see if it holds a vacuum and then replace the R/D and fill up the system with freon.
