The drawing you see on this page is for illustrative purposes only.
Your driveshaft may not look EXACTLY like this illustration, but the Bill of Material shown is the Bill of Material for YOUR driveshaft.
The illustration may show a driveshaft with an end fitting that is a slip yoke, but your driveshaft may have an end fitting that is an end yoke. In that case, the part number for the end yoke is shown in the bill of material.
The illustration may show a driveshaft with flange yokes on both ends, while your driveshaft may only have a flange yoke on one end. In that case, the Bill of Material will say “NO FLANGE YOKE” for the item number where there is no flange yoke.
