1967 Dart differential question

Hey Fabo

I have a 67 dart with the 6cyl A/T and what i was told a 7 1/4 rear end
it also has the large bolt pattern axles in it. The guy i bought it from said it came out of a 67 Cuda, With no other info.
The lug studs are definetly wider spread than on the front wheels.
and the back side of the rear end looks like the same kind of style as GM 10 bolt pan facing the back, not a 3rd member type.

Im new to the wonderful world of Mopar, so forgive me if seem a lil lost.
Lol, i am, Now with out me goin out and tryin to get under the car to take pics, what im simply trying to find out is, Im selling it, and i am just making sure that im not gonna sell it for give away cheap, nor do i wanna come off greedy, i was told also that the axles could be worth more than the rear end,being the large bolt. I am just looking for a ball park range,
I was thinking around $150
Or could the axles alone be worth that or more?

Any help on this would be greatly appreciated.:prayer:
Thanks
