Well if anything you must mean "half" a bolt-on then since only about half of the engine to trans bolts are used and the other half of the holes are empty without Steve's kit. :-)
You're also forgetting that a custom flywheel is needed.
Either way, what you're selling is just a bevy of stock A6 2.7T parts. There's no "complete kit" here. And there's also a lot more work that you have to do than shave the block. If somebody reads this and thinks oh great I'll snatch this "complete kit" up and have my mechanic bolt the 6-speed in over the weekend, they're going to be sorely mistaken and disappointed. Just thought that needed clarification since this is far from a "complete kit" needed to swap a 6-speed into an RS6.
