8.75 Yoke Question

I am having a problem getting a proper u joint for my 8.75 yoke. My problem is that I purchased a 489 4.10 chunk and want to link it to my 7290 drive shaft. The measurements of the yoke are 2.091" between the ends and 1.06" diameter. I purchased a 7920 to 7260 combination u joint and that did not fit the diameter. Then I purchased a 7290 to 1310 u joint. It fits but there is no room for any type of clip. I have attached some pictures. I also need straps which did not come with the chunk. What type of straps should I use? I realize strength of the small joint is an issue but I want to see if the 489 chunk is worth spending money on the large yoke. Hopefully someone can help solve my issue.
Thanks
Steve
