Hello,
I do not know of a description of how to replace the evap. core on paper. I did my first using the fly by wire method. I just started and stopped until I was done. If you are doing it to save money, you are not saving money, but wasting time. If you are doing it for a learning experience, I commend you! Good luck and take your time (and some digital pics to reference) and you will have fun.
