Doug and All: The Chrysler specification for sill to floor is 8.7 inches for the 300H (both coupe and convert). So your 9" car is real close. Sort of surprising assuming there must be some difference in radius between the original bias Blue Streaks and a modern radial. This is just a guess, but perhaps the 11" car had the rear springs re-arced such that the rear was higher, so the front torsion bars were just turned up to level the car. The forward, short, part of the rear spring should have a bit of recurve downward. 300ly, Gil C. In a message dated 5/20/2010 3:57:47 P.M.

Both cars have 15" wheels and identical 235-75R-15 tires. H1 was built in April 1962, has new Eaton springs and KYB gas shocks. It has an average height measurement of 9 inches. H2 was built in November 1961, has original springs (possibly re-tempered), and new original equipment hydraulic shocks. It has an average height measurement of 11 inches. Did something in the manufacturing process change from November 61 to April 62?
