Single coil P/U in Thunderbird housing

[CokeyW]

I want to swap out the two EMG humbuckers in my Everson bass for single coil. The bass is routed for Thunderbird housings and I don’t really want to spoil the look of it if possible. 

I was wondering if anyone makes single coil pickups in a Thunderbird housing? 

[verb]

EMG make their Thunderbird housing with a single J pickup inside, or the TW version giving you single or dual coil options. I'm sure some of the custom pickup manufacturers would make you a suitable pickup.
