Series 2 & 3
Standard LR springs are handed. The right hand side is slightly heavier duty to the fuel tank (and in UK cases the driver!). However, most parabolic manufacturers do not differentiate between LH and RH.
Yes we do. We've seen various manufacturers of parabolics and they've always used standard LR bushes for the rears. Part number is 548205. Take a look at your front paras. They may well also use 548205 (like our British made ones). Some of the Indian manufactured paras such as Britpart & Bearmach use a larger non LR bush on the fronts.
You get 2. In other words the kit does both ends of the axle.
Yes you are correct. However, the SWB variety fits perfectly as they fix to the rear crossmember (which is the same for SWB & LWB).
Yes they fold up.
Yes they are vinyl. Sorry we don't do leather.
Defender door mirrors come as singles. They aren't handed, you simply turn the head around 180 degrees.
