Front tire size?
Either should look fine. The 215/65/15 will be 26" tall, which will probably be as tall as you can go and you may need to do some minor trimming at the front or rear corners (or both) of the wheel openings.
The 205/65/15 would be 25.5" tall, which would be about the same as a 225/60/15. I ran 225/60/15's on my '74 Duster with cop wheels before I upgraded to 18's, you can see the bottom corners are pretty tight on the tires even with those.
