Polished cast baseplates have the 3 lines.
Team trucks with cast baseplates have team on one side.
Forged baseplates have the lightning bolts.
We don't have a forged pro truck in stock but I will assume they too have the lightning bolt.
Close.
We only have one mold for casting the baseplates, which has about 100 casting cavities on it, and the individual casting cavities alternate the patterns. so all three are essentially the same (thunder-bolt, TEAM, or the three lines - which is actually supposed to be a thunder-bolt flag, that Jim T drew long ago). They are all assembled randomly though.
All the forged baseplates are the same, with a lightning-bolt, and a 'Thunder' on the opposite side.
Hope this clears things up!
