widow actuator & parts

my driver side window in my 67 lark 2 door post keeps slipping out of the channel support on top of the crank actuator assembly that seem to work fine without jamming.

looked on opgi and all i could find was a new repro of the actuator but without the channel.

anybody know if some makes repros of these or am i lookin for salvage?

thanks for the help guys.
