put a little spot weld at the end of the yoke, just big enough to hold the cap in place. i believe spicer makes a strap with a tab at the end, i'm not sure if they make them for the gn yoke (1350 i believe) its worth asking. but either way using new caps should provide plenty of clamping force to hold a cap in place, if they are reused they will be stretched and out of shape and then you have a much better chance of losing a cap. very few people know it but the straps are designed so the tabs aren't flat at the bottom, once it is torqued down for the first time it changes shape a little and fits perfectly. but it will only fit perfectly once, re use them and it won't have the same shape and stregnth (not an issue on 90% of the cars out there, but good thing to do anyways).
