Thanks! For the record I don't want to go full bosozoku, just kyusha or something. Coprone as hell is the exact name for the style. Anyway, I finally found my old Nardi Classic steering wheel from my basement. As my Toyota had a broken adjustable steering column, we just removed it & placed the rack a little bit higher. That was a lot work, but imo worth it.
I also got APEXi FC controller installed. It's quite good & useful. It's for showing engine RPM, ignition timing, speed, battery voltage, temps etc.
My second favourite installation are my Pioneer TS-X10. They really match the aesthetics of this shakotan sedan, yes they are just small details but I love details. And they work too, so win-win.
Got the mandatory train handle & rear lip on my car now, too.
