diablodoc, just like Sam said, making a connector is pretty easy.
Now back to the build, I have been working on the interior and trying to fit everything has been a challenge. When I first molded all of these pieces from an OEM car they all had the leather on them. Needless to say, these pieces are far from perfect because of that and making them fit correctly has been difficult. Anyways eventually they will be done and upholstered.
These carbon fiber pieces where made by Jose "lambocars" and they are amazing, he gave them to me as a present when I met him a couple of years back in Barcelona
These are all the pieces for the top pillars and the headliner installed. Still have a lot of fitting and trimming before it is finished but its starting to take shape.
Here I cut some 1/4" marine grade plywood for the upholstery behind the seats that hides the firewall.
