Dirtyswiff

I was hoping to start a thread where members can post their fixes by replacing a series 1 part with a series 2 part. I've gone through several threads talking about only individual situations with individual swaps and on certain parts . This would be a great sticky for new owners to see a compiled list on 1 thread of all the s1 parts better off replaced with an s2 version also why or why not. (Keep in mind replacing, in this thread, means it fits and or fixed the problem.) plus I wanna know more info. Haha :
