Uneven LCAs help

Could be a prior owner had a broken or sagged T-bar and installed whatever they found at the junkyard. If the factory paint marks are still on the T-bars you can tell what you have, or if you carefully measure diameters with a vernier (but not where the paint sags are). Kind of hard to read the numbers in the car. I wonder if circle track racers every purposely install mis-matched T-bars.
