[FC] Rampside lower A arm ball joint question.

[Paul Steinberg]

In the serrated flange screw or bolt, the ridges under the head are to secure
it in a locking fashion against the metal.  These bolts are usually used in
high vibration situations.  My guess is that it is used on only one hole as a
safety measure in the event that the other one came loose and fell out.  If
you would like to see an example of this fastener, go

  I am rebuilding the whole suspension on my 61 rampside.  It is all
  dissassembled, cleaned, and ready to reassemble.  The lower ball joint is
  secured by a stud at the top, and two 5/16" bolts on each side.  One of
  these bolts has a regular head with a 1/2" flats.  The other has an odd
head
  that has 9/16flats and a raised circular section above that.Total head
  height is about 1/2".   The new ball joint (MOOG) also came with new bolts,
  and one of these too, is like this odd one.  Question is: Does the odd
  headed bolt go to the front of the vehicle or the rear? Also, what in the
  world does this special bolt for? GM wouldn't spend money this  for no
  reason.
  Great site.  I have owned Corvair cars for a long time. (presently have
  three) but this is my first rampside and the learning curve is pretty
steep.
  thanx.
  George.
