Two questions:
1) I see control arms with slotted shafts and those with slotted shafts utilizing a "slug" to apparently hold them in place. My question is whether the slugs are necessary (they can be pricey themselves and you don't know which ones you need until you check caster), or do the slotted shafts without slugs stay put where they're bolted?
2) When I last bought upper arms from Mastersbilt, they said I needed a steel shaft on the LF because aluminum would bend. Do most agree with that or has anyone had any experience with an aluminum shaft on the LF bending?
Thanks in advance!
