Hey Emtea,
I love seeing how much you have progressed the car in a few short months, it's helping to motivate me into getting back into fixing up my hachi.
I have seen some people tape and paint the Zenki headlights to look Kouki and match the grill a bit better. I have tried to find a write up but can't find one. Could be a cheap alternative to forking out on some Kouki Lights.
As for the hatch, thanks for the info on the hole, I have bubble rust in the same area so now I know when i fix it i may try and plug the hole with some rubber, maybe a rubber wiper block off?
Once again good work and keep up that progress!
