At what yoke? Are they too big or too small? Are they too small of a cap or too big, Too short of a cross?
My U-joint catalogs are very far away so I can't look them up but my 3 rears are all 1350's = 1-3/16'' caps with a 3-5/8" cross. The only other difference is if they are inside or outside lock-up. The next size up is a 1410 series = 1-3/16'' caps w/ 4-3/16'' crosses. The next size down is a 1330 = 1-1/16" x 3-5/8"
Try a Google for Neapco. They have an online catalog. That's the brand AZ used to sell.
Napa used to sell Precision brand and they have conversion joints if somebody did something odd to your driveline.
Also.. Check the straps. They are the weak link.
ICANFIXALL... Stop Yokeing around, You'll get thrown out of the Joint...
sorry, but you started it..
