[pugs]

It should be the same taper, and if you can lengthen the drawbar it should be good, although I seem to remember someplace had a "pullstud" with female threads in it that fit in the NMTB spindles, put it may require shortening the drawbar a tad.. You may have to remove 1 drive lug for proper alingment. If this is the case you may want to add a modified lug to where you removed the one so as to keep the spindle balanced yet, but not to engage the toolholder.
