We have bought a 1.6 16v for Sophies first track car. It's a PH1 mk2.....T plate (looks like the PH1 172, not the Williams) I'm trying to get some powerflex bushes for it, but I don't know which ones to get. Underneath the body panels, what is it? Is it similar gear to the williams shape or similar gear to the PH2 172/182 shape? I have asked powerflex and the sales "rep" Laura, has said thats its the Williams shape items that I need. On the powerflex site it misses out the PH1 172 shape completely and just goes from Williams to Clio 2 shape
