I need a Rear ! ! ! !

I have a 66 dart, had the old 9bolt with the small carrier. Can't find one anywere so it looks like I need a rear. Who has one ?
wish list is 3.55 gears, but I will take anything but must be a good rear.
I need 5\4.5 bolt pattern just bought new crager SS and then the rear pops, Yes the axels were updated from the 5\4. but that was done before I got the car. Any help or info on a rear would be great.
I'm in NY 11746

thanks
Corey
