Got a great diff from a 1966-7 datsun bluebird I thought it was a h190 but its a h165 4.11 (37:9) with alloy carrier and is the same size drum to drum as the 1000. The beauty about it is it fits the 260z alloy drums and its all lighter than the original h145.
Now Being looking at some diff ratios or the crown and pinion and wondering if anyone knows if I can mix and match h165 pionions. If I use a 35 toothed crown from the 4.4 rear with a 10 toothed pinion from a 3.9 rear you can in theory get a 3.5 ratio rear which will go fine with a 4 speed a15 on the freeway. Does anyone know??
