using U12 pintara discs you need to:

re-drill discs to 4x100mm to mount to hub
machine out centre of disc slightly
grind caliper to clear centre of hub
possibly grind caliper to fit under 13" rims (depends on exact rim)
you may also have to grind a little fat off the pad itself on the inside edge to clear the hub, cant remember but srb210 mentioned that

no spacers required, no changing to caliper mount just straight on to stanza mount
caliper mounts to the back side of the car (in relation to the strut)

i havent put a set together for two years, but have done it twice before, srb210 is in the process now

slotted U12 pintara discs wernt very expensive, cant rememeber exactly how much
you can order them as blanks so that when you re-drill them you dont have two sets of holes, though it can take 6mnths to get them this way as they make them specially for you when they do the next run of that disc

oh, and looking at the diameters posted, U12 would be much better as even with a U12 disc the outer 2-3mm of the pad doesnt touch the disc and essentially hangs over the top, so with the other discs listed there would be 7-10mm overhang of the pad to the disc i beleive
