AutoCad 2D :: Keep Dimensions / Deleting Leaders And Comments

I do a lot of taking other peoples drawings and incorporate our portion of work onto theirs and often shrink the viewports to our sections alone. Their drawings often have information that we don't want on our drawings to insure we are not responsible for the work. Presently, they drew the detail in ms and annotation in ps (which i personally think is retarded).

I want to keep the dimensions but not the leaders and comments. Is there any way to delete all mtext and leaders quickly without deleting dimensions. Only think I can think of is highlight dimensions and convert them to ms via modify then go into ps and ctrl A and delete.
