TRNW-2: 10R80 pump bolts

[Steve Everett]

  Thanks Randy !   good o know ,  oddly enough the seals on the Ford bolts
remain in good shape after removing them , unlike the aftermarket ones
where the sealer is flattened and destroyed after initial tightening,
 I'll play close attention to the condition of the seals, but I intend on
reusing the bolts, unless I can get new ones from Ford,  I do not like or
trust the aftermarket ones
