About To Just Give Up!!!
I would never buy something like a crossover u-joint from a box store. There are plenty of great drive line shops or there that I would be calling and having one shipped to me. Fortunately for me, I used to work at a very good one and it's only 5min from where I live.
I will also add that I'm not a fan of using crossover u-joints. If you are on a trip or something and it fails, it's to much screwing around to have a parts guy find you the correct part. I would much rather change the end on the driveshaft to 7290 and just use a standard u joint.
