Both the 8.5 in 10 bolt (car only) and the stock 8.875 inch 1/2 ton truck 12 bolt came with a 1310 series pinion yoke. Can't say what the PO of your diffs might have changed and I do not have the sizes for the 4wd or 3/4 ton trucks. The neat thing is the heavier 1330 and 1350 yokes and the 1310 yoke are splined the same so almost any driveline shop can get you the parts to change from one to the other.
Joint Width Cap Diameter
1310 3.219 1.062
1330 3.625 1.062
1350 3.625 1.188
