That is fantastic work. I am in awe of your level of patience. My son and I are currently doing up one of these where the white ants got to the cabinet and backbox. Luckily the only good things left were the backglass,  playfield (mylared) and the electricals. I think it is much easier to make a new wedge head backbox and converting the donor cab than the job you are doing. Just amazed at the lettering.
