mx73 front brake part identification

I am rebuilding the front brakes on my mx73 and the brake kit (from protex - K1365S) I received didn't come with all the parts that I require (I have or the seals for the gaskets) - it is missing two.
As per the link below (now toyodiy has no images) I need the two different rubber covers?? that the two 47715 pin's slide in two.

I cant seem to find the part numbers for these parts anywhere and when I called toyota the parts guy had no clue ( later found out I can get a complete kit but it would cost $80 for one in aus )... any help would greatly be appreciated.

Cheers

The part you need is called a caliper bushing kit, it is available through Napa and is pet number 82783 for the front calipers and 82925 for the rear calipers, each kit services both sides.
