Oil Seal R&R on my Dart - taking her back to the shop

Are you saying they worked on it, took those pictures and didn't bother to check to see if the bolt was broken or tighten it if it was not?
Sadly yes, He was very apologetic about it though. The U-joint gave him some issues, so he may have been a bit rushed. He wont make the same mistake again.. He is a good mechanic, just not familiar with real old cars, but he & his 2 person shop are very eager to learn, so Im getting a break on labor. Im just super glad I looked closer at the pictures. Have no idea how long its been like that, could have been decades, the cover looks like it kept it from backing out further.
