if i had to use the indys i would set them up with the element deck.
Yes that is what I was thinking, Indy trucks on the longer wheelbase BBS wood Element board works, the Ventures on the Alien deck with the shorter wheelbase.
The 7/8 bolts on the Ventures as they have the lower forged plates too.
The normal 1" on the Standard Indy trucks, no risers on either needed with normal size wheels.
Spitfires on the Ventures as a more tech street setup, maybe OJ (as cruiser) or Slimeballs (as normal rider) on the Indy trucks as a park / transition / all rounder.
