1. Leak Detector
2. Acetylene torch kit with tank and 3 tip sizes
3. Spare Nitrogen Tank
4. Blower and Pulley pullers
5. Calking Gun
6. Refrigeration Scale
7. Refrigeration Oil Pump

Caulking gun is like $5 so thats no big deal to me, the rest seems like bs tho. Id put riveter on that list too as something you shouldnt need to supply, for the most part you can use self tappers instead of it.
