Oldskool - I think the problem here is that you assumed that the Wico replacement handles are a "kit" that will let you change an 8-way to a 4-way joystick.
Oscar, what was received in the kit was 1 "8-way" joystick base, 1 ball handle, and 1 actuator (8-way .600"). Also received were the e-clip, spring, and 2" washer.
The bill of materials doesn't call up a base, but does call up two actuators, and labels the kit as 2-4-8 way.
I bought this off of EBay as I needed a 4-way joystick. Was it packaged incorrectly by the seller? Perhaps, but it looked official to me.
Does the paperwork in the box accurately reflect what I received? I don't think so.
Am I really upset about it? No, not really, except for the fact that I traded the .600" actuator away for a .500", which results pretty much in a worthless joystick.
Is the trade my fault? Absolutely, but again, I feel that the paperwork in the box was a little misleading.
In my opinion, what I received was a 8-way joystick, and it should have been identified as such. I based my decision to purchase on the scan of paperwork.
That's all......
