Brian,
Why not do it yourself, I did mine on my 90, the biggest job is getting the old ones out but there is a way with a hacksaw, cold chisel and a wood chisel. Oh and the standard LR tool a hammer.
Put the hacksaw blade thro the bush, cut the steel liner taking care not to cut the actual rod, then use the cold chisel to collapse the metal sleeve in on itself, the wood chisel is the easiest way of cutting thro the old rubber.
Takes about 30 minutes per bush.
Putting in the new poly bushes is literally one minute per bush and its done by hand with a wee sprinkle of soap (fairy liquid) to help it slide in.
I did the complete front in a day, that was all the bushes on the radius arms, the panhard rod etc. The hard job is getting the bits off.
