They have data sheets for all of their tires there, I used the specs from the Radial T/A here, other models will be a bit different. You should be aware that the sizes are a range, so it's a good idea to get the data sheet if you can, especially if you have chosen a size near the limit of what will fit. Unfortunately, BFG doesn't offer a 13" Radial T/A that will work well, these are 14, 15 and 16 inch:
P195/70R14 (all, good replacement for 1960 - 65 6.50-13)
P205/70R14 (all, good replacement for 1966 - 69 7.00-13)
P195/60R15 (all, good replacement for 1960 - 65 6.50-13)
P195/65R15 (all, good replacement for 1966 - 69 7.00-13)
P205/60R15 (all, good replacement for 1966 - 69 7.00-13)
P205/55R16 (a little tall, may rub on an early, fits lates)
Late models have a little more room in the rear, you could use these sizes on the rear of a late if you want the "big and little" look:
