[TR] threaded rod

[Gary Nafziger]

As randall suggested I found threaded rod to take out the forward leaf spring
bolt and promptly twisted it off right at the head of the bolt.  I think it'll
be easy to pull out with an extracter.  However in shopping the web site i
quickly became confused, not knowing the meaning of metal ratings.  I know 5
is pretty hard and 8 is very hard but they don't seem to have those strength's
in the size I want.  Is B7 hardness good enough? 
thanks!
