Now the car was drivable again, I drove it myself to a company to fit in a roll bar. The thing is that I wanted a copy of the original IROC bar but a bit further in the back of the car, as far away from my head as possible, I do not wear a helmet in daily traffic

.
So it is loosely based on the original IROC bar but more to the back and a bar for the seatbelts on the passenger side as well.
Had to pull out most of the interior...
