[Healeys] side shifter

[James Shope]

i have noticed that my bn6 with side shifter seems to shift less smoothly than
the bj8.  it will grind slightly going from 2nd to 3rd if i do not hesitate
slightly when shifting.  is this a normal thing or are my synchros getting
worn.  they looked good when i had the trans apart, but i was not familiar
with the brass synchros and may need to replace them.  everything else in the
trans looked really good and so far no problems other than this one.  can you
put steel synchros in these older side shifts with no problems?  TIA    jim
