semantics.

both the supercharger and differential lack a drain plug.

that does not have any bearing on whether or not changing
the lubricant is advisable.

 

We do work on cars here, but for the most part, they are of the carbureted persuasion. Our shop is better suited to handle mechanical restoration projects; people will send their E-types to us and Dick Maury (head of our rebuild department) will rebuild their engine/transmission/etc for them.

We have been known to do an occasional service on a few newer cars, but those are few and far between and we typically end up having to schedule those around other projects. If you're having difficulty locating a mechanic to help you with this repair, feel free to contact me offline and I'll be happy to provide you with a few references.

 

Thank you for the clarification, Bryan. Dick did mention that they have installed drain plugs in differentials for some customers, but I wasn't sure if any other work was done on newer cars.
