Hi All: I have a 71 Barracuda Gran Coupe with 383+4 auto. I have no broadcast sheet for it. It has the following info. on the original door jamb decal
F78x14 LOAD RANGE B
3402332

My question is: Which tires would come on the car originally? GG's book lists a whitewall F78x14 and a blackwall F78x14. From the information above is there any way to tell which one should be on the car. Thanks everyone.
