Well you could kill a few birds with this stone ;p
RA60 Struts w/ AE86 Spring cups welded on (Unless the RA60 items fit).
RA60 Lower Arms (Power steering variety for shorter steering arms for less turns to lock)
RA60 Calipers and Discs redrilled to suit hubs
UZ??? Crown Hubs (5x100, AU Falcon on...)
You will also get the benifit of bigger brakes and a larger stub axle.
Just my 2c, but thats what id do
Oh forgot to mention, the UZ crown (late model w/ 1UZ-FE) is not an aussie delivery. So you will need to source parts from a jap wreckers.
