from what I have read/found online,
the Spicer replacement driveshafts would use the imperial size Spicer 3-2-159 yoke with dimensions to accept the 1.187" (30,2mm) X 4.187" (106,3mm) UJs
where the original driveshaft yoke was the 32mm X 106mm UJs
the discription of your "new" UJ appears just to be wrong A/B dimesnion
