I received the Toyota 4AGE equaliser shaft/layshaft (from a AE101/AE111 Corolla/Levin) late last week for the price of a bottle of spirits :) and had a look at it over the weekend. In the pic below, the main CV cup on the drivers side of the engine will be removed and spline of the layshaft inserted into the gearbox. The standard mounting bracket will be removed from the shaft (2 bolts) and a custom one made up to fit the Starlet engine and mount to the old alternator mounting points.

However I quickly realised that the support bearing on the shaft has quite a bit of movement in it so I put the bracket in the vice and measured the vertical movement which ended up being 9mm at the end of the shaft which is 360mm from the bearing (pic below shows the shaft lowered (main pic) and lifted (shadowed in red). I initially thought that this was going to be a problem but after talking to a friend who works for SKF Bearings, he said it may be like that by design, allowing the shaft to pivot slightly and once the bracket is bolted to the engine and the inboard end of the shaft is inserted in the gearbox, there should be no vertical movement of the shaft within the bearing casing. As a precaution, I checked that was no lateral movement in the bearing itself and after also talking to a guy at a local transmission shop, he indicated that the bearing is fine and confirmed there is really no need to replace it.
