hey guys, i’m looking to replace the hori buttons on my hrap3. i’m really new at this, so i’m not sure which buttons to buy. i am looking to buy from lizard lick.

which of these buttons will work? i’m interested in particularly the Seimitsu PS-14-KN 30mm Pushbutton with Vertical Microswitch.
also. can anyone tell me how to replace the ball top? do i have to open up the case?
Any Japanese pushbuttons will fit.
You will have to open up the controller to change the ball top.
These guys are right. Pretty much any japanese 30mm buttons will work, even longer ones, like the OBSF-30RG buttons.
how about the start and select button? what size are those?
24mm.
well yes any 30 mm japanesse push buttons work and 24 mm puch buttons to but to make the installation easier you should get the ones with out the screws and made for metal tops
as for ball tops just about all sanwa balltops and seimitsu balltops fit it to but if you want a sanwa battop then u have to get the adapters to go with it
i’ve been reading around and people are saying different things about the screw ins. one tutorial says that the nuts will not fit for the X button because of the metal plate. anyone have experience with this?
i really want those transparent buttons from lizard lick, but they are screw ins 
It can be done, but apparently you have to sand the nut down a bit to make it work.

compared to the hrap2, it seems like there is considerably more room between the X button and the joystick plate in the hrap2.
screw ins should be no problem?
