I wonder if the dash can be changed to one that is from an A series with the key on the left ... personally that is my favourite. I would make sure to have a lot of insulation in the coupe if you want to be in a comfortable car without too much noise.
I believe Greg's coupe does have the key on the left. Either way, I do plan to have a left side key on this build.
It will have a LOT of insulation - similar to how did my Speedster build...
