They are the 1"-16 left and right hand, I checked that on both the 48 and 53 2 tion axles I have.
Looks like a lot of them listed on ebay for less than half price for the pair, I'll double check everything tonight and try a set if they still look suitable. (trying to fit Spicer axle/tierod arms) They do look right for the original 2 ton axle.
