are they the same or different?

i picked up a 99 GSR bb/mc for my brake conversion on my civic but i decided i didnt want to bend and reflare the lines.

so i picked up the 99 RS MC recently and noticed its slightly different from the brake booster from a 99 GSR.

my questions are...

Would i need to get the brake booster from an RS?

would it be able to install on the GSR BB?

would i be able to use the booster from my vx?

 

any one?

 

someboooodyyyy i need to knooowww

 

RS is different from GSR/LS/RS master and booster setup in 99. i don't know which would fit an eg without modification.

 

i'm not sure about 99 for RS but for 94-97 .. RS runs on a 260nm-v booster .. and the mc is 15/16" .. and gsr has always been 290nm-v-2 ..
