Hunter, Unusual makes his arms to tuck wheels with drop spindles. Chris does good work. I used his cross shafts on my upper arms. He made the arms for this Mazda, tucking 20s with drop spindles.
You can use either spindle. The drop spindle will have less camber when laid out. Since you have the drop spindles I would use them. Just let Chris at Unusual know which spindles you use so he can build the arms accordingly.
