I have been mucking around with it today, its from 1982 model Mazda B2000/Ford Courier, I have stripped it down to do some more measurements.
The overall length(outer axle to axle) is 1360 where a esky(MK1) is 1350
The spring mount centre is 935 and my MK1 is 938, so yer its good to go, i have to get wider U bolts as the new diff tubes are 5mm wider(big deal) and the shocker mount plates have enough room to be slotted to suit the 5mm(2.5mm either way)
The axles have semi floating hubs and can remove the axle and bearing assembly without losing oil from the diff, the bearing is fully enclosed and dont rely on the oil from the diff for lube, there packed and sealed from both sides(diff and outside)
The big bonus with the axles is there is a dust seal for the outer seal, it has to be removed for the placing of the new studs, now that dust seal is riveted on with a PCD on the rivets of 4/108, so yer no need to re-mark it out, its ready to go with a slight re-drill.
Got some machining to do tomorrow and ill get some pics up for you guys to inspect, next thing is to pick up my MK2 diff to swap the bakes over and ill keep the pics coming.
Ill be doing a full write up once i get started into this whole car a little further
