From what I've read, there are two possible options for my truck (98 K1500 w/ 4l60e + 10 bolt). I'm trying to swap in a 14b SF but I need to know which conversion joint to buy. Again, from what I've read, its either a S44 or a 1330. What's the best way to tell? I do have calipers and can measure but I don't know exactly what to measure or what it should be.
