Looking for stiffer arb's. I've got 22mm front and 12mm rear. I've found a 26 mm front, but want an 18mm rear. Any idea where I might get one?

I'm trying to sort out the handling on a recently aquired 4x4 (2.9, '89)

Having fitted some Koni's all round, there's a big improvement, but I still can't believe the roll connection between the steering wheel and the back end. All bushes seem ok. There's more roll on the whole car than I like, but most especially the back end, which has a mind of it's own. Bump steer? This thing handles worse than many a 60's british sports car with a rigid axle and leaf springs!

So next plans are to increase roll stiffness, and use poly's at all roll bar bushes. I don't want it lower, don't want it stiffer......just want it to behave itself!

Help and advice gratefully received,

Al
