This is a really solid setup. I was going to do it, but ended up going with the Jeep conversion. If I could have go the money off I would have done it... oh well, too late. The rotors would be very easy to modify adn a good shop that still turns rotors could easily make the modification. The Gen 2 and Gen 3 seem to be the same as I did the Jeep conversion on both without any issues. Another benefit to the disk's over the drums is that if you break an axle they may keep the axle in the truck long enough for you to get it hauled down.
