has anyone any experience of doing the rear beam bushes themselves? mine need doing i believe now and i already have the bushes just need to know how easy it would be to do at home verses a garage fitment. if its not worth my while i wont attempt it, i know i need a bias valve(early cars only) so i'll be having to bleed the brakes at the same time, and i realise i need to press the bushes into the beam, just wondering if its a possible job at home or best left to the garage?
