My rear passenger side axle bearing went on my 72 1200. It's the 62mm OD one, not the more common 72mm. I ordered the bearing from Nissan, but when it arrived, it turned out to be the larger one. Unfortunately, and stupidly, I cut the old bearing off before receiving this bogus bearing. And now Nissan is telling me the bearing has been discontinued from Japan! I'm hooped!

I've phoned around town, and no one in the Datsun circle has the bearing, or even a spare axle with bearing on it. These cars are getting extremely rare here in Canada. So my only option seems to be to buy a whole b210 rear end and swap out the old 1200 one. I've been told I'll have to shorten my propeller shaft, perhaps even weld the rear u-joint from the b210 on, and also fab lower shock mounts.

Any suggestions or tips before I go down this path?

surely there are specialist bearing suppliers around you somewhere that could get a bearing to suit....just need the ID OD and thickness of the bearing and they should be able to help you out

Well, there are standard sizes of bearings available, but Nissan didn't use one here. Apparently standard practice in the automotive industry to keep customers from buying them from any old bearing shop.

Another solution might be to turn the axle down to 30mm, which would then accept the standard 6206 bearing. But I'd also have to make a 1mm walled tube to space the axle back up to 32mm nom. to accept the hardened collar that goes on after the bearing. The hardened collar is what the seal runs on.

Just put a B210 rear end in. It is stronger.

1974: direct bolt in
1975-1978: use the B210 driveshaft

No welding needed. Just use coupe<->coupe or sedan<->sedan, as the rear assemblies differ.

just swap to the b210 rear set up and grab he tail shaft to suit too, should not need shortening then.

Im using b210 h150 rear set up with corresponding tail shaft (so the yoke suits) and going to use the same rear set up with a h150 auto tail shaft once L series swap happens.

If psrts are stil available for the b210 set up, easier to convert and buy a few spare bearings than machine down your existing one to suit.
