Yeah, I have also considered the 9".... I guess we're trying to find the right compromise... It hurts me to put a ford part into a holden car. For the conversion I expect I would need 9" housing, lsd centre, the axles, brake discs, full conversion... and then how to the coils go on? Are they just coil overs on the existing mounts...? Are there any diagrams or something that would show us how to do it....? again, it hurts me to put a ford part into holden...
