Suicide doors bag kit?

I ordered a bag kit for my 72 c-10 and when it got here i noticed that there were no no fittings in it for the air lines. So I call them up and they say that fittings don't come in their kits. That seems like a pretty important part of a kit to me, but I did get 50 ft of 1/4 in air line that will rot in my garage.
