Replacement tuners and nut for ibanez RG

[Transcend]

its a hardtail one so i just need a standard nut however this is an area in which my knowledge is lacking

i have no idea whats available and what difference it makes so some info would be great here.

and what brand tuners would just be a straight swap over as i dont want to be drilling the headstock.

Thanks

Tuners should be now problem
I would suggest Gotoh ones as that is the same as Ibanez would use
Check the position of the fixing screw though
