Emergency parking brake adjustment

[Frank Blackstone]

The Anchor Screw #2 , that adjusts clearance of anchor bracket, is missing from the emergenecy parking brake on my P15. I have installed a replaement screw but am wondering if  a nut is needed somewhere in the assembly. The manual picture does not show or mention  a nut but it seems to me one may be needed. I miss Coatney being here to  edit my posts to make them more understandable.

No lock not but gets a wire thought the hole in the bolt head back to the bracket to maintain your adjustment as per pic. in your post (wire Not shown but hole is).
