Tony 2311, I totally agree.
Many years ago I replaced a full set of bushes with Poly ones front and rear on a Rover 220 Turbo Coupe and it made a surprising difference.
Steering was sharper and there didnt seem to be an increase in harshness despite the fact that Poly bushes are stiffer.
The side benefit of Poly bushes is the fact they are a doodle to fit..They dont need to be crushed in as Rubber ones do.
The secret would be to get all the diameters and bore sizes required and then aproach the polybush suppliers..
As D1gger5 says, some will be a standard size..
Not strickly true as the rear ARB on my Capri were cotton reel shaped and had to be squeezed into the bush holder using a variety of tools (bush tool, flat screwdriver, sockets, etc).
The first set I had to fit (mid 90's on my first 2.8) to the front lower suspension arms were the same - now they come as a two piece bush with stainless steel sleeve for the bolt.
The usual problem with the bushes is that after 10-30 years in-situ and they are a pig to remove (bolts and bushes weld together, inner bushes sleeve and the rubber come apart and this cannot fit through the chassis/subframe section, etc).
If a dealer and bush numbers can be found then identified on here then this is useful to so many.
