I have been searching this for a couple hours and have not come up with defiant answer. Every thing i have read is that it should work with a longer bolt. Can any one confirm this?

Anyone?

This describes putting a A/B-crank pulley on a W-Crank… not the other way around....

The crankshaft front tip was lengthened by 18.7 mm (0.736) in. The crankshaft pulley width was increased by 13.6 mm (0.535 in.). There are now two keys instead of just one.

This said it should work. I did some more searching today and found a post from butter saying he used a used a w series pulley with the ab crank on his cressida. I am going to try it and see what happens.

I finished bolting everything up this morning and it works. I swapped the power steering pump, water pump pulley, and crank pulley from an 88 NA. I did have to buy a new crank bolt as the one from the 86 na was to short and the one from the 88na was the wrong diameter. The bolt i used was fastenal pn 11114730. m12x1.25x100 10.9 grade.
