I believe that the offset/bent bracket should be toward the center of tractor on both right & left sides. The right-side (looking from seat) in your photos looks correct. The left side has the brackets transposed. Normally there should be approx. 3 inches between shields for very small plants (wider if plants over 8 inches tall) We always set the right side about 3/4 inch closer, as thats the side we always watched.
Another thing is the shovels on each side of row/shield should be half shovels so you don't push dirt to close to plants.
We also set the shovels closest to row about 3/4 inch higher than the shovels between rows. This (shovels between rows) loosen up a lot of dirt there & took out the weeds as that's were most got a start, also the center shovels were about 8 inches wide (called wide sweeps) & they wore very fast.
We did custom planting, cultivating & thinning of sugar beets, cabbage, carrots/etc. back in the early 1960's with a 2 row setup @ in 28 inch rows. Usually the shields were used for first time cultivating of corn, - soybeans usually the first 2 times thru.
If someone else says I'm wrong about the placement of shields on a MH, that's ok, our setup was on an Oliver 60.
