Hi Bill;
By the book, you want the front and rear counterweights to match the genera= tion of the rotors ->
86-88 =3D Series4 (S4),
89-92=3D S5,
93-95=3D S6,  S5 and S6 are supposedly the same.

rear CW - a few quick searches will turn up more - going rate ~$50-60. &nbs= p;Dealer probably 2.5 times that.

front CW:
The S4 and S5 front CW are different although they look very similar.

PS - more than a few engines have been assembled without being told this - = and they ran just fine.  Although, best to try to match.
You should have nothing else to worry about your assembly.  Are you go= ing to give it a good street port?
