Decided to make some Street or Track UCA knockoffs, I like the design for its adjustability.  They are .5" shorter than stock with a 10 degree ball joint angle (~about 10 degrees less than stock).
 
Tapping the tubes, this was a lot of work, I have never tapped 3/4" holes this deep before in steel:

 
Bending the tubes on my home made tubing bender. 1" OD x .156" wall steel tubing bent easily at about 5000lbs:

 
Tubes and Plates (got the plates water jet by one of our vendors):

 
Designed a weld fixture and had it printed on our 3D printer:
 
 
 
Welded Assy:

 
Cross Shafts on the mill:

 
Painted and Assembled with QA1 rod ends and new Moog Ball joints:
