Monster Beetle rubber shaft boots

[Billy01]

Does anyone know that when you convert a stock hex style dogbones for a Monster Beetle / BlackFoot to a Thorp Diff setup do you use the rubber long shaft covers with the zip ties, or do you leave them exposed without grease? Any help please...It will be for a semi-runner.

The Blackfoot runner I purchased locally, which had the Thorp setup, had the stock boots stretched over the Thorp dogbones.
