Radius rod is the bar that bolts to lower control arm by two bolts 17mm heads and back at 45 degree angle to a bracket - it is at this bracket these bushes are designed for.
I recall being sold these to fit my 92 Brumby , and of course ended up going for a Super Pro listed (correctly bush that was for 92 Brumby. They fitted

Kept these Pedder units intending to shove in my GLTA - though it is now finished with...moving on to the Vort and they'd wanna fit - same colour as the car

The kit comes with four bushes, 2 of ML180A and 2 of ML180B ID 19mm

bit of a disappoint at first to see superpro list GENII as being 1979 to 1994 but, at least they show two kits of strut bar bushes, one for MY the other for L Series, so, they only list one kit, maybe there is only one bush set for L Series including Vort......
and two metal sleeves that reduce ID to about 14mm
Just now find this kit is also listed for the Bitsa Starion so maybe the sleeve is for their radius rod - must be only thing scrawny on a Staz !
Anyone got any part numbers to help decipher the difference of the Ls radius rods bushes listed by Pedders then ? - could save me some grief once pulled things apart
