Fsa headset cup question

[JLav]

I have an FSA Pig and getting the cups in was a huge pain. If i get an FSA orbit mx can i use my old cups or will it screw it up?

Probably won't work to be honest.

no it won't work, the orbit mx is sealed and needs a 36*/45* contact on the bearings. the pig is unsealed so no
