Thanks Scooby. I understood about the master cylinder itself needing to be swapped. I was wondering just about the fluid resevoir since that usually isn't included if you buy a new master cylinder. I saw that the question had been asked in post #37, but I didn't see that anyone had posted a response.

Thanks for the great info. Does it look like the brake fluid resevoir from the Legacy master cylinder would snap into the STi master cylinder?

I noticed in various parts listings that there's a different part number listed for WRX brake boosters with an automatic vs manual trans. I would assume that the WRX manual and STI boosters are the same. Has anyone with a 5EAT LGT installed an STI booster? I looked through the two threads on the STI booster swap but some folks don't have their trans listed in their info.
