Went pretty smoothly as described. I used an egg crate marked for each step where screws were removed to keep them all sorted out (OCD vs. old age). Only other tip was that in step #5 the rings and screws at the corners of the back seemed to be integrated and came out together, the rubber feet came up by pulling from the side - didn't really require a thumb tack. Otherwise, having the right tools (described) made it a snap.
I agree - having the right tools is the key to this going smoothly. It would have useful to have more detail around where the long and short screws go on the heat shield. This is minor niggle and overall good instructions.
