Answer: D581 and D580 coils look similar, but the actual size is somewhat different. The D581 coil bracket can be used for most truck generators, and the D580 coil bracket is suitable for some luxury LS1 starting from 97.

Brackets look really nice and are very well built. For my coils like in the picture you will have to put spacers under each bolt. I used oversized nuts as spacers and bought longer bolts.
Its very clear some people are buying the wrong brackets and not using the reference guide for which coils they have. The bracket is great.
Everything bolted up perfectly with the stock valve covers. Comes with all the hardware to mount the bracket and the coils. Little tip when reusing the old coil harness is to put it behind the bracket when bolting up to hide the wires.
Great products I look at their stuff first when buying LS parts??
