Hrp pedal box what wheel cylinders on drums?

Hi I've just fitted a hrp pedal box with o.625 and 0.7 masters 
Looking into placing an order for new brake internals on my rear drums … I see there are 2 different sizes 
I for without pressure regulator 14.29and
1 for with pressure regulator 17.46 

May sound like a silly question but which one do I need cheers 

Presumably that's the bore of the slave cylinders, so measure yours, or if a gti then you will have the regulator, non gti non regulator??  I forget, so regulator or not I guess.  or do you mean should it be different with the pedal box.

Yeah mines s a gti but didn't have the compensator and now I'm running pedal box without compensator so do I go for the one that matches without regulator? 

I think you should go for the gti type, I don't know the specifics of your pedal box, but normally the balance between front/rear is adjustable, so that's your compensator.
