seat belt help...74 deluxe coupe

Hey everyone....



I've been looking all over but figured you might have some great suggestions of where i might be able to look that I haven't thought of yet.



Got a 1974 corolla coupe deluxe with the 1600(2T) and I'm in need of a new drivers side seat belt, you know, the one with the kill switch in it.



I've tried many placed but I know there are more that I don't know about. If anyone has any suggestions, I'm open.



Thank you

Jason
