One sure change is drivers floor pan. Don dropped the floor and made it out of metal vs CR I fiberglass. The CR I used Mustang II style motor mounts which nobody would go back to but a CR I might have upgraded to CR II mounts. Don added angle behind seats not sure when but it’s in the threads. Some of us CR I added it but lack of angle would indicate CR I. More changes Don made are in the threads
