You've selected a Sterling 10.5/10.25 1410 U-bolt style yoke with the pinion seal, pinion nut, and U-bolts. 

1410 U-bolt style yoke for the 1993-2010 Sterling 10.5/10.25 with all the fixing's (pinion seal, pinion nut, and U-bolts).  The Parts Mike yoke is FORGED, U-bolt style, features FULL LOCK UP, and has an OE spline fitment.  Our design achieves the highest possible angle while maintaining strength.  See the write up below for more details.

• FORGED will beat the same part made from billet, or cast...period.  The forging process forms the metal grain along the contours, and results is a stronger part.  Forging also compacts the grain structure which nearly eliminates failures from voids or inclusions.
• U-bolt style is superior to straps in nearly every way.  The U-bolt is nearly impossible to shear, but the head of a 5/16" bolt in a strap can pop like a pimple.  There's nothing to peel back on a U-bolt, but the strap can get caught.  Plus the U-bolt is simple to identify, a 1410 u-joint takes a 1410 U-bolt.  Straps have all sorts of different length, width, and thread pitch differences for the same size u-joint depending on application.
• FULL LOCK UP is what we call our u-joint cap retention method (see pictures for FULL LOCK UP vs little tang).  Almost all yokes have a little tang to retain the u-joint cap.  Catch that tang on a stubborn rock, and it breaks off.  Then the cap shoots out, and BAM.  FULL LOCK UP eliminates this problem by fully retaining the u-joint cap.  
• OE spline fitment is what every yoke should have.  Most yokes slide on, and aside from a gross error, work just fine....BUT an OE spline fitment requires encouragement from a 3 pound dead blow.  It would take hundreds of thousands of miles to wear out splines, but we make them so they'll NEVER wear out.
