I've finished submitting a new suite of parts for the earliest version of the garage door 822 (and its frame 821). This is the version without studs, and with tabs on the frame for use with slotted bricks.

The new parts are on the tracker here:

Frame

• https://library.ldraw.org/tracker/32685 (full tabs)
  
• https://library.ldraw.org/tracker/32686 (partial tabs)
  

Door

• https://library.ldraw.org/tracker/32695 (shortcut with door and counterweights)
  

Appreciate any comments or suggestions!
