Placebo heater help

Next weekend I will be installing my factory heater setup I bought from a member here for for cj5 fhead 59 and wanted to check if anyone has any good info on where I should source parts for my bypass hose that I assume im now needing. the threaded pieces into the block and does anyone have some pictures showing where the shut off valve on the firewall should be mounted at, and where the control cable for the valve goes through the firewall to it?


This is the shut off valve im planning on buying unless someone else has a better one to suggest
