SBC 350 78 GMC K25 engine mounts and traingle brackets?

Getting ready to drop my rebuild in truck these go in between block clamshells and block itself does anybody remeber the orientation and which one goes to which side of block and what direction?

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.
