You can NOT be sure about yoke sizes from the chassis or engine numbers, or model or year or anything else!
Whole prop shafts will interchange, and you may have a shaft with the other sizes of UJs fitted as a replacement complete shaft. The FLANGES should be the same fitting to the diff/gearbox flanges at each end of the propshafts, but the YOKES inside the flanges may be the other size.
Measure them!
