Agree with LinPark on this. Simple mod with hand tools and can be done faster with a lift for sure. But still easily done in 2 hours.
Glad your mechanic has the DIY to walk him thru it though... shouldn't be an issue once they see how simple it is. I was scared sh!tless about doing it myself at first too, now I do it over a beer (literally one beer's worth of conversation) and I'm done.
