4" red ball top joysticks?

[Crayola]

I've been looking for some Wico 4" red ball top joysticks but they are tough to find.
(used on Robotron cabinets).

Anyone know another joystick that's similiar? Leaf would be nice but not necessary.
I need a pair for a Multiwilliams project I am building.

Saw some 4" Wico Red Balltops recently, don't know if the base, grommet, and leaf switches were available with them - you could look into it further by following the link Cheffo posted here .

If bases not available,  post a WTB in B/S/T  and keep checking ebay- you may get lucky. 
They do show up if you're persistent and patient.  If not, there are alternatives.
You could put Wico balltops in a Happ Perfect 360 joystick (no microswitches-was used sometimes as a replacement for Wico Leaf joys).  Divemaster in B/S/T could prob hook you up.

You could check with Pixelhugger here for Wico's (microswitch) to see if he has any left. They were unused NOS - think they were 3.5".
If you top mount 3.5" balltops, would work out to about the same as 4" bottom mounted (assuming a wood panel used).

Good luck.
