Good luck with your build. I do not have a Micargi but a Supercycle 70th Anniversary Cruiser (Canadian Brand), stripped down that looks very similar to yours. I also have the same forks and misjudged the need for Spacers. I also have some ordered.
Our Motors are different and in hindsight i wished that I had ordered a Grubee like yours......
Anyhow, I am also painting my gas tank, chain guards and parts of the Motor.
