If you can find a 120Y Borg-Warner tailshaft, it's the same length as the Sunny one. The problem is the rear flange is wrong. The only rear flange that will work is from a Series 1 bluebird single piece tailshaft. These have the same 1 inch universal joints as the 120Y shaft. I've got one under my Sunny wagon. Hopefully these are a bit easier to find. The other alternative is to get the stock shaft machined out to take the 1 inch uni's. Why did they peen the bloody uni's in, that's what I want to Know!
