Transmission help

[FLYIN-9]

Well I've struck out with the Ford dealership in finding out the gear ratios in this transmission. I know it came out of a 79 or 80 Mustang. The numbers on the tag are - D9ZR-FA 140142. tHEN ABOVE IT, RAD-AA. Any info would be awesome..... F-9

RAD-AA - The list that I have says that this is a 2.57 in 2nd gear

Thanks for the info!!!
