I lengthened the chase and the back seats are the same depth as the front. I'm going to tweak it. Make the back seats shallower, it'll look more like a coupe. https://www.flickr.com/photos/162402231@N05/?
I've rebuilt this after a break of around 30 years. As a 9 year old I always wanted to do something more with the car and here it is, back seats.
Hopefully, I'll motorise it and change the gear ratio so all 3 gears work.
