Looking for STOCK 1967 8 3/4" Dart rear end assy drum to drum

Looking for STOCK 1967 8 3/4" Dart rear assy drum to drum.
1. Can be from other A bodies as long as they are 100% compatable with 5 x 4" pattern.
2. I would prefer late 1966 to VERY early 1967 manufacture date but will entertain other dates / years if the price is right.
3. Don't care if it is any form of limited slip or not.
4. Needs to be within day round trip driving distance from Denver. Prefer east side of the rockies.
5.Prefer Good used but needing total rebuild is ok if the price is right.
6. Prefer ratio in the 2.9 to 3.25 (will be used behind an automatic) but will entertain other ratios.
7. Drums don't not be reusable as long as they are correct for the application. IE. diameter width etc. can be aftermarket but application correct, don't need to be flared or finned
8. I'm not in a hurry so if you know you will have one available in a few months to a year I can wait, but can buy anytime if the price is right.

Thanks
