Crossover steering is easy to install on Chevy trucks. Simply detach your 4WD steering box and replace it with a 2WD model. The box mounts are identical, but the pitman-arm indexing differs between the four- and two-wheel-drive models. Dan started his crossover system using a 2WD box plucked from a wrecking yard but upgraded to an AGR-built box after the junkyard jewel puked its mechanical and liquid guts out. The AGR box is plumbed for a ram assist, which will be added some time down the road.
