If I am using a 1986 Defender 90 front axle and an R reg discovery 300 rear axle what sort of polybush kit do i need. Just one set or are there different types ?

I would double check with the supplier but off the top of my head you would only need the earlier kit (to suit your front axle) as the width of the radius arms changed which may or may not affect the bushes.

The A frame and trailing arms should all be the same along with the trailing arm and radius arm to chassis bushes. Panard rod to should not have changed.

I fitted Superpro bushes a couple of months ago and had no trouble with them and they have been great.

as above earlier kit
