30 rear radius rods

[old31]

What are the two differances on my rear radius rods?

The right one has more of an indented end. The left one is smooth.

Sure looks like one is upside down or you have two right side ones

1 appears to be an early rod and also appears to be upside down.

The right one is June 1928 thru May 1930 and the left upside down one is April 1930 thru end of production.

Upside down may indicate a substitution from one side to the other. There should be right and left units. Folks tend to try and use whatever they could find as far as replacement parts. It's not unusual to have mismatched parts on these old cars.
