the bridge bar/shock bar is weld on, as are all the axle tabs (including the shock mounts) and the stepnotches.
The truck we just did a 5 link on at the shop had a plastic tank. We test fitted the shock bar in a few different spots on the notch until we got it as best we could. Move 1/4"..tack...test..cut...repeat kinda thing. We got it as best we could, it kinda hits at MAX lift now, but just barely, and nobody drives around like a monster truck anyways.
I know people HAVE switched to the metal tanks. Try your luck on s10forum with this question and someone should be able to tell you what to do about your emissions.
