Question for all you oldtimers - we just brought a really nice '50 Chrysler convertible into the LeMay museum, and while inspecting it on the lift noticed something strange. Strapped crossways to the rear crossmember is a steel tube about 3" in diameter and 30" long, sealed at both ends. On one end is stamped "gyrostabilizer mfg Los Angeles". Any idea what that might be? I tried a Google search but nothing looked related. I'm guessing it was one of those questionable add-ons often marketed in the past, but would really like to know. Anyone?
