I am looking for a stock differential cover that has been modified with Drain and Fill plugs. I did find one being offered by SLP though it did not have the Fill plug. I don't need looks just function. This modified cover should pay for itself through dollar savings (gaskets) , time and anxiety. With all items in place I could imagine changing the differential fluids in 15-20 minutes tops using one shop rag.

Does anyone know of a reasonably priced aluminum cover that has the Drain and Fill plugs?

Is anyone willing to make these stock/modified covers and sell them for a reasonable price? I don't want to pay $139 for an aluminum cover unless I have the differential that needs the support. Thanks.
