We recommended the 73-87 for years, and it works just fine with our kits. It has a slightly larger hole in the steering arm for the tie rod when compared to the 63-70. We have received feedback from some customers regarding some inconsistencies in the taper. Some reported that while drilling the spindle arm to 5/8" they only had to drill through as little as half the steering arm. This just makes the 63-70 a better option. The 71-72 and the 73-87 will still work, and are safe to use... but if you are going to purchase new spindles we recommend the 63-70.

Thanks for the quick reply.
I knew there had to be a good reason.
