Which powerflex front ARB bush do I need?

[Squirrelofdoom]

Hi guys,

Have purchased (but not yet fit) powerflex bushes for the front arms, rear suspension and dog bone. Want to do the front ARB at the same time, but I see that there are three different sizes? 17mm, 19mm and 20mm....

Powerflex
Powerflex
Powerflex

Am I being stupid? How do I know which size I need?

Car is a 2000 APY (with the larger 45mm front wishbone bushes if that helps)

Thanks guys,
Aran

I had to measure mine mate, there was no definite way of telling other than measure

I guess the different measurements are the diameter of the ARB itself? Should be easy enough to measure

Yeah mate, easiest way is with a calipervernier, can easily reach behind the tip and measure the bar
