Hehe i just noticed u said the SOUTH SIDE of adelaide, and Sleeka Spares is kinda on the other side.(north).. BUT Its worth making the trip out to pooraka every now and again, dave is a gun when it comes to early toyotas and parts in my opinion..
Otherwise u could try Toyoland Auto Wreckers or U-Pull-it, and see if either of these mobs have a used item around.
Or even ring Action Suspension Engineers, and see if they can source parts for it..
Dave mite be able to get the bits tho, he managed to find a few suppliers of bits/bearings/seals for my RA2x steering box rebuild.
