Does anyone know if the EPS / Steering rack on the GX550 is the same as the ones on Tundra / Sequoia? I am in the process of modding my GX460 to the EPS unit via custom fab & minor tweaks as necessary. If the parts are identifical to Tundra, then I don't have to wait for the GX550 to be rolled out and sold in volumes. Any info (confirmed info) would be appreciated.
