PA18 Weight STC

I'm curious about the gross weight STC for the PA18, and didn't find anything specific with a search. What all is involved with that? I've heard about bigger strut forks, and seen piece of brace tubing for the rear seat, surely there's more involved than that.

Brace on the rear seat, beef up of rear spar and heavy tube on gear leg is what I remember from looking at the stc.
