Yeah that's right funkymonkey and thanks for the site. I'll most likely get a kit from www.airide.com.au as they make bags to fit lots of different vehicles and they are a very high quality manufacturer. I don't know if i want to do a bolt on job or do a full bridge and 4-link setup with a monster notch and big tubs etc, OR forget the bags and find a suitable air strut kit, which is probably what i will go for.
Have you heard of "built not bought"? Most custom mods can be done in a shed and i have seen some very impressive fabrication work on showcars/minitrucks that they have done by the owners themselves.
