Brake Disc Choice and Size and Pads

[braveheart 3]

Hi Gents,
Just refurbishing a 93 4.3 Chim and would appreacite your advice.
Firstly what are the correct brake disc sizes for this as these are about to be changed we have standard wheels.
Next thing is what would you recommend just OEM or cross drilled , cooling slots etc ?
Finally what pads would be the best just for road use and mostly town driving.
As usual any help would be great.
