Well it has been over a month sense I got a Waltersons gear box for my HL panther g.
This is what I found, it is .032 too high or about 1 mm. The wires too stiff and attach screw too small. I emailed them with my problems and they said they would get back to me.
This was before the new year and nothing as yet. It would be better too low than too high,
you could shim it up.
