life is getting better!!
Are you going to change the inside door lock position on the door so it looks like a 68 door? That will be a dead give away that they are not 68 doors.
My dad had built one before when he restored his 1968 Coronet, I don't know where he originally got the idea from but I can ask him, its a really simple design and i dont even think we did many measurements. It was pieced together with what we had lying around except the two long pipes it rolls on, because why do it nice when at the end its just going to be cut up.
I built the brackets for the doors which didnt take long at all and we used the back bumper mounts since they were damaged anyways, I'll ask him to chime in for the specifications of it.
Here are some photos i have of it when we were building it
