FFR said they were going to make a video for the build to help everyone so I'm surprised there hasn't been anything yet after a year. I'll have to ask them about that. Most of the sequence of things in the manual makes sense but there is so much more instruction needed. I planned on doing a video of my body build but just wanted to get it done like most due to an event coming up of us so I passed. I ran into a lot of what you described and just re-finalized the front end and my gaps are much better even with the aftermarket headlights which were a serious pain. the rear trunk is a challenge as well and I sacrificed a large gap towards the front to minimize at the back. Doing a body on an FFR car is like doing a lot of things, it gets easier once you've done it and can wrap your head around it. Until then you will make mistakes. Having done a few of them I have some extra holes and elongated holes all over this car! Still, a build video would be huge.
