7 Leaf Spring Spec.

[Ralph B.]

I'm looking for the "free arch" spec. for the GM F-41 leaf spring. So far I've been only able to find the 9 leaf which is slightly over 10.0" --- I believe the 7 leaf specs out considerably less?
Thank you,
Ralph

Yes, the hand annotated notes in my copy of Noland Adams' Vol 2 book, Specifications section, say 7-leaf free arch is 6.25"...
