1971 Duster 340 4 speed numbers matching

Might have an interested buyer. Besides the paint, transmission, turn signals, and bolt pattern, has anything else been changed from factory that you know of? What rear end is in it? Is it a numbers matching 8-3/4" with LBP axles?
Thanks.

Mike,
The rear is the original one. The gears were changed to 4.30. As far as I know 8 3/4 A bodies never came with large bolt. Thanks forgot to add that. Some engine bolt ons are not original.
