Looks great, it is a absolute rare G10 with a very beautiful interior!!
But for me, the steering wheel is on the wrong side 
Thats not so strict, old cars without catalytic converters have the following limits: (all at engine idle at about 950 RPM)
CO Vol. 2 to 3 %
HC up to 660 ppm (unburned fuel particles per minute)
Thats all the about the emission output limits here for old cars...
Are those watches around the ash tray are available?
I see that you have here very good looking water cooler tubes, where can you get it?
The original one are not more available (and the would be only as texture rounded tubes, so they are not the best). From what car the fit or come from?
What do you think is it hard for me to get some such tubes or such a watch from PK? Here are all those parts are not availabel and if you driving with a G10 to any Daihatsu dealer they all from the office comes out to look at your car, they don't see any G10 since more then 15 years ago. (so mean nobody have a good knowledgement of the G10 here
)
