Don't know if this will help, or confuse you, but does your front conversion push the wheel out, or are the hubs in the original location? This may be of concern. A 50 is a shorter tire. My car is stock, and I have 7 inch all around with 235-60-15. No rubbing what so ever. With the round wheel wells, you may get away with a slightly larger tire than a 69. Hope I didn't just confuse you.
