hey guys,i can answer that!! i used hilux diff out of 1978 hilux,later model diffs after that year are too wide..i paid $150 for mine from wreckers,but you need to change the centre before you do anything!!! mine came with 5.9s,now you can't change just the gears,you have to change the entire centre!! carrier changes with different gear sets!! i picked up a highace van centre with factory lsd and 4.11s for $90....also these diffs are 30 spline factory axles,there basicly cheap and bullitproof!!! you need to have spring hangers on the diff moved slightly,i had this done and a custom tailshaft made with new axle bearings done for $400......so about $650 all up depending on what you want.................tramp rods,go to wreckers and get lower rear control arms off 82-84ish rear wheel drive corolla,then get lower rear arm mounts off 1990 front wheel drive nissan pintara,these are bolted on via two bolts,they simply bolt under stock corolla leaf spring mounts..the front mount requires a fabricated triangular bracket..which you need to make yourself...all this basicly gives you tramp rods and only cost me $80 pair..............................PHOTOS!!! ive sent dan some pics of madtoy,hope he got them and can put them on here for me,so hassle dan..he he he... hope all this helps..cya
