Quoting from the Haynes manual, copyrighted '74 and '78, Chapter 11 :
TR-6 Number of working coils = 5 1/4
Rate = 312 lb in.
Free length = 10.03 in.
Fitted length = 8.12 +_ 3/32 in.
Fitted load = 925 lbs
Hand of helix = right
Static deflection = 3 in.
Wire diameter = 0.5 +_ 0.002 in.
Many other specs listed regarding suspension & steering. This manual
covers TR-250, TR-5, and TR-6, more or less completely (although the
available manuals and their contents have been an occasional sore spot).
Best regards,
