Im making new arms for my truck but im using the Fabtech 3" lift spindle. Problem is I need to drill/ream out the holes (theyre tapered for the ball joints) in order to run uniballs. Question is can I? A few buddies of mine said it can be done, but wanted to get some more opinions. Im not sure if it is cast iron or steel? Also the lower hole is tapered to 1". Is there a uniball with misallignment spacers that I can run with a 1" bolt? Any help/advice would be greatly appreciated. Thanks guys.
