As for seats, anything out of a small car is useable. I have used some SB barina seats/Suzuki swift seats with some success.

For the remainder of the parts. How much of a hurry are you in?

I have some of those parts, but my time is VERY limited right now, so I wont be able to hunt through my shed for at least another 6-8 weeks.

There are plenty of others on this forum who might have what you want, before me, and also just a fraction closer
