The new so called MT4.5 also is listed as a taper per foot of .6240, where South Bend lists most of their propitiatory tapers at .602 as per the factory South Bend literature I posted earlier.
It is a simple task to create this part with the lathe it will be used on. It is a short engagement and the offset compound will produce it. There is no need to wonder where to purchase this part.

I agree Paul the so called MT4.5 is a more recent made up designation created to explain what for years what was known as a proprietary taper.

just for reference, i have a friend that has a heavy 10 ... but it has a d3 chuck, and we think it takes MT4.5 spindle centers. it also has about a 1.25 inch spindle hole.. kind of a rare beast, apparently. it is a qc with starwheel clutch engagement and has a taper attachment ! ... and underdrive. hmmm .
oh, we can't find a MT4.5 adapter anywhere, but at least he has the taper attachment to make some.
