Sold in USA as "ARB Dana 60 Diff Cover"
Even if you buy from ARB locally be careful & don't use the bolts supplied as they are imperial for the D60, you have to go to the Bolt Shop & buy some 10x1.5mm cap head screws to suit, The Salsbury is Metric.
plenty of beefed up covers to chose from depending on your flavour

I like the ARB one because it has a horizontal filler hole & dipstick, you can pour oil straight in from a bottle. But it does annoy me being red, because I have heard myself thinking 'what a ******' when Im following a car with a painted red diff cover.
