I've had a search around and found some useful info on here but can anyone give me some advice on what they've experienced first hand?

I currently have NO rear swaybar at all (ke70/hilux diff) due to having a 3" exhaust that had no room for the bar to go on when the new diff was put in.
But I'm now planning on moving the exhaust around so I can run one on there and thinking of throwing a front bar on aswell.

What sort of size's front/rear should I be going for? And what have people been paying lately new for whiteline non-adjustables?

Also, correct me if I'm wrong but do us ke70 owners need to use a 86 rear bar due to whiteline not making them? The only difference being the wrong size bushes?
