Here is a pic I took from the 65 FSM showing the different tire sizes, rear end ratio and what speedo gear is used with eachimage.jpg

I’m going to guess that your 205/70 14 is gonna be around the 735 to 775 size and the gear will be dependent on what your actual rear gearing is. Bear in mind that your original tire size was not 14 in but 13 inches.
