Need driveshaft for 1968 dart 8 3/4" rear

PLEASE! If you have one for sale follow the instructions in my post and SEND A PRIVATE MESSAGE as I requested at rhe beginning of the thread. DO NOT repliy publically here!. People keep posting "I have one" publicly which is the same as advertising it to the general public.other people looking for the same item send pms to the person through my ad and then suddenly the item being offered to me,that im already communicating with the seller about with privately is gone. It defeats the whole purpose of my posting a wanted to buy ad,where the item is supposed to be offered to the person who is looking for the item and created the ad solely.
Everytime I've posted an ad the same thing happens. This site has a for sale section to offer items to the general public.
This driveshaft is the last piece I need to finally get this car back on the road after its been sitting for 6 months and its frustrating to lose a part because other people are sending pms trying to get something that was offered to me.here because it was posted PUBLICALLY instead of sending me a PM.
I really hope to get this car completed soon,it was my daily driver and will be again,if I can ever get this last piece! So close.....
