I am using castelated nuts to secure the rod end bearings in place. They will get cotter pins when finally installed. Sonce the fittings could be subject to rotation, I decided on the castelated nuts.
Now I need get the bolts welded into the chromoly tubing.
With bolts taped in place in the chromoly tubing, set fit to make sure threads would work
