It's the same as the Z32/S14/S15/R33 brake pad.
I used Schneider

pads that are intended for the Toyota Prado/Land Cruiser around the early PB* series I believe and removed the "low brake pad sensor" by cutting it off with a chop saw. All of $125.00 for pads and they're still going strong after 1 year with the only downside being a lot of brake dust. I've since lost the box so I can't give you the part number.
The low brake pad sensor is simply a piece of metal that is fastened to the pads on the inner side and protrudes a lil', my guess is it gives off a squeal when it reaches the rotor.
I believe the Hilux that everyone speaks of is the one around the TAY model but I couldn't find the one that matched my pads.
Oh, if possible get a larger brake master cylinder to help push the extra piston surface area.

Only then you'll really feel the power of the 4 pot.
