Would it be possible to make a machined billet centre casing for a common lsd centre as that found in 200sx and other independant rear ends but to suit a live axle setup with bolt on axle tubes? similar to this one on the link? Then with custom axles (the second most expenive bit) and using pintara brakes wed have a strong lightweight diff with many common lsd centres to play with. Common any ideas from anyone for something similar?
