sorry have not been on here in a long time. i posted how to fit a m78 torque worm style center into a m70 front diff on facepook and discovered you cant search the info anywhere but face pook and i want people to be able to find this info. so many diff people will tell you that there is no lsd that will fit a m70 and there non serviceable diffs this is not true, the m70 center is based on the m78 irs center only difference is one bearing carrier is 22mm closer to center and where the passenger side axle slides in needs sleeving, i had a mate machine my center and press the sleeve in then i fitted countersunk bolts and chamfered edges of center, also had to grind down a lump in the housing,the bearings are the same as m78. this was not a hard job only issues diff center is made of very hard metal so tungsten or ceramic cutter needed and assembly is time consuming to get clearances right because of the clam shell construction. i used a torque lock diff center from tuff, it works great, amazing traction and great road manners on the street even on roundabouts anyone with a adventra or a territory should do this mods it makes a great car so much better.
