Are you asking how to get the FC lug pattern on a FB???

 

Or are you saying you have the second gen conversion and wanna know what the actual pattern is? more details on what you are actually asking please

 

i want fc stud pattern on fb.

 

There's alot of info on this already. Either swap out your suspension and rear end for the gsl-se parts to get the 4x114.3 stud pattern, or buy the re-speed big brake kit to get the 5x114.3 stud pattern, which uses TII brake parts.
