Your local Pirtek(or similar) will have schrader valves,, buy two, also a metre of airline, also two push-in connectors,
maybe $25??
Jack the rear CHASIS up,, leaving the wheels on the ground,, cut both airlines(CHASIS!!) inside the comp box,, push on the two schrader valves, use your 12 volt air pump to inflate the bags,, or at least put enough in them to drive to a 240v compressor:p
That should give you breathing room,,,
