After looking at the photos, I might have a bump stop extender that will work for you left over from the lift I was going to install in my Vitara.
Have a look at the pic below and look at the pair of shiny, circular bump stop extenders with the stud to the left of the blue diff drop brackets.
This is an OME Bumpstop extender for the Suzuki XL7 (Part number FK23 from memory) The centre stud is a 10mmx1.25 thread and they are 50mm in diameter and 20mm high. So all you would do is to unscrew the bump stop, cut down the bolt to 10mm (The instructions for this kit said you had to do that on the XL7) and screw it in.
RRP of this kit is $26 from ARB for the two extenders, and I'll post this brand new unused part to you for $25. You'd just need to check the thread on the hilux is a match, but if it was say 12mm, you could drill it out and retap it.
