Do the 03 a arms have tapered ball joints? I want to buy a set of upper ones b/c I think the lowers are tapered but the 02 uppers are not. Also Can I use a banshee spinndle on the blaster if I get the 03 upper a arms?
 
From '90 until present, all Blasters have a tapered shank lower ball joint and a straight shanked upper.
