67 K-20 Lockouts

[O'l Buck]

Does anyone know if anybody makes an aftermarket replacement for the old style heavy duty spicer lockouts? The ones I have are the ones with the aluminum dial and six 3/8 bolts holding them on. I'm having issues with them wanting to stick, well, at least the left one. It will lock if I monkey with it long enough, but I'm not sure it's engaging all the way and I'd hate to tear one up when I'm axle deep in mud.

Thanks,
Chad
