Hi , I'm using my lockdown time to build a non functional reproduction mkII STEN , I have the set of basic dimensions posted on this forum but there is doubt if they are accurate, can any one with a genuine STEN help me out ?

Those plans do have errors.
Perhaps the best single source would be David S. Findlay's Firearms Anatomy Book II The Sten Submachinegun. (Book I is the M1A1 Thompson).
Keep in mind that there are numerous variations in how different parts and subassemblies were made. The rear end of the trigger box in Findlay's book is a less common variant.
