1966 Valiant heat only blower motor

*found a new one, thanks for the help everyone.

Desperately seeking a good used or a new blower motor for a 66 Valiant.This is for a non-air-conditioned car. Or does anyone have a part number/company I can order from that is dependable.
My blower was acting funny and now I know why. The plastic card that holds the brushes was cracked in several places and cut up.
