Metal plugs for my house address set are missing. I believe the metal plugs are what the screws go into in the wall. If I find plastic wall plugs that fit the screws do you think that would work?

No any extra wall plugs required for the installation. Your installer needs to drill holes in a wall and push the letters with metal screws inside the holes, that’s it. Metal screws are going inside the holes without any extra plugs. See the attached image please.

I had a question for you regarding the home sign. During installation I applied a little too much pressure to the “L” in lisgar and started to notice a crack. I was wondering how much would it cost if I were to have the L replaced.

Setup for the laser cut machine is rather expensive and the min order is $50.00 even if I cut one character only. If you want me to cutout the letter L, please pay $50 + tax = $56.50 and I’ll cut it out during 2 business days.
