Part number is 66-761 in the manuals. I don't need the block, but the cover ran and hid someplace, and the Mazda parts farts say that part is "retired"

Don't know how it can retire, it is only 25 years old!

 

You can get the whole positive terminal/main fuse block for a reasonable price.

Ray Crowe may have it cheaper than Atkins.

Also, I think that part number is the number in the diagram, you have to look it up on the chart to the right to see the actual part number. In this case the block assembly is FD02-66-760C
