A lot of aftermarket valve covers have mounts for LS3 coils that won't work with an LS1 coil pack because the bolt spacing is different. LS3 spacing is 72 mm while LS1 spacing is 64 mm. I've created a simple adapter that offsets the hole enough for you to run your LS1 coil on an LS3 coil type valve cover.
