Can anyone advise the factory settings for both front and rear springs for a 1912 T
-eyes centre to centre
-compression value of new springs
Thank you in advance
Andy Ruffles.
Wide track or narrow?

David,
The work sheets I have for Hendersons Springs for a standard front spring (7 leaf) give the leaf lengths and the center to center measurement for the main leaf.
The CC measurement in inches for the main leaf is -31 5/16" to 31 1/2"
Also stated is Average rate of deflection 531 lbs.
In large writing on the bottom of the page it states (this is the one to build)
Hope that is of some help.
The spring length for wide track and narrow is the same and I don't think there would have been any need to change the spring rate.
Anecdotally I was told by an old spring bloke that an extra second leaf, (the first one in the pile) will add around 10%
He's going to retire soon!
