Kind of embarrassed to post this but I must. I am finishing up the restoration of a Bally Judge Dredd, which has taken me two years to complete, but had to move the parts around from room to room due to family needs. Consequently, I lost track of the location where 12 identical #6 nuts go and now have these left over having reinstalled everything else. The nuts were definitely from underneath the playfield but I cannot see them on any of the many photos that I took. However, I only took photos of under the playfield AFTER I had removed most of the items from the top of the playfield.
This is my first major restore and rebuild and I have definitely learnt my lesson to bag and label everything and to photograph extensively BEFORE removing anything.
The nuts in question are small #6, and of the standard, non-locking, variety. I believe they came from around the top end of the playfield (i.e. somewhere under the Deadworld I believe but I could be wrong it was so long ago that I removed them). If anyone can shed any light on where these nuts go I would be most grateful.
