I have bought and owned both a WE conversion and a complete WE kit.
The conversion has no oils or lubes. This is becouse all the parts that would require these oils and lubes need not be rebuilt to complete the Standered BJ4 to a WE Conversion.
Both the Standered BJ4 and the WE come with all shock oil and diff lubes to complete the car direct from J-Concepts.
