Default 68 Firebird Tire Combos Revisited

I have done many searches on many forums and I still don't have a conclusive answer. I have a 68 coupe that I need to put new tires on and I'm trying to pick a front tire to match the rear.

I will be using 15X7 Rallye II wheels at all four corners. I plan to use a 245/60R15 on the rear to help with the 3.90 gearing. The BFG chart shows the 245 to be 26.6 inches tall.

I would like an approximately 26 inch tall front tire. The same BFG chart shows the 235/60R15 at 26.1 inches and the 215/65R15 at 26 inches.

So, that's the question: 235/60 or 215/65? Any pictures of either combo would be appreciated.

For reference, the stock F70-14 was about 26.2 inches tall. As the car sits now it has 215/70 and 225/70 R14 tires front/rear now. They are about 25.9 inches tall in the front and 26.5 inches tall in the rear.
