So, I got my Model M in the mail today and I've put all of the blank black keys on minus one.
I cannot get the spacebar on. It is about an inch shorter than the stock spacebar on the keyboard and the stabilizer on the left side (not the metal piece but the round connector to the left of the spring) is too narrow on the keycap and is too tight to have free motion. The spring section and the stabilizer section are the correct width on the keycap but it's not happening for me.
Am I doing it wrong?
