Update: I checked with ron ayers, and the air box changed from 02 to 03. They would be interchangeable, but different. I think , but harder for me to confirm, that the GPZ's are also different.

^ My mistake on the boots. But when I removed my air box it was a pretty tight fit. Is the gen1 the same as a gen2 as far as clearances removing the air box?

The air box is a little tricky, not a lot of wiggle room. It was easier for me to get the air box out, after removing the carbs. @Saabnut the "springs" hold the boots to the air box, there are clamps to hold the boots to the carbs.

The rubbers can be changed with out removing the air box. Disconnect the carb side first, the air box can be pushed back a little to do this. Then remove rubbers from the air box. Install the new ones in the reverse order. It is a pretty tight fit, but it can be done this way.
