G'day mate,
I fitted a later model hilux into my MK1. I used Nissan A32 discs on the rear. They will basically bolt straight on. You may need to lightly file the inside diametre to fit over the diff hub.. I also used the calipers and hand brake cables.
I have some escort strut to 5 stud adaptor for front complete with bearings and seals. If you like. These were purchased incorrectly and have never been used.

cool, thanks. i see some caliper adapters there, what are they? and what wheels are they? do they fit under the escort? do you need a special offset?

I made the adaptors up using 12mm high grade aluminium from the metal merchant.
The wheels are 16x7 superlites with a 12P offset. Im not sure if they will fit under standard gaurds as i have arches.
