Not sure if anything changed over the years, but the lower bracket in your pics went on the passenger side with the 5.7 donor block that came out of a '97 suburban. The lower flex plate cover (heavy aluminum) and torque rods from that suburban also all bolted right up to the T400.
Love the parts interchangeability on these old trucks.
