oh dam,
Got my arms from Opentracker Racing products due to this from the website
Excerpt: Improve the handling of your classic Ford with ORP's Standard Upper Control Arms. ORP Standard Upper Control Arms are designed for the classic Ford enthusiast looking for a performance edge without breaking the bank. We have the shaft kit taken apart and de-burred, pre-lubed and properly adjusted with the tab welded on to keep the shaft kit nuts from coming loose. These arms also work very well with the 1" upper control arm drop for added performance. Fully assembled and ready for installation with new ball joint and 90° zerk fittings.

One nice area is the welded tab on the shaft nuts that will keep them from undoing themselves. Just one more option!
