Hello all, I have a question regarding drive shaft lengths. I have two 70 Satellites that I am converting to 440's with auto trans and the 8 3/4 rear ends. I bought a drive shaft from a member in FL that said it was from a 70 Road Runner and it measures 51.5 inches the charts tells me that it should be 53.64 inches in length. Does anyone know for sure which one I can use, it is the same drive train as the 69, I was not aware of any differences in the length of a 69 over the 70, the car uses all of the same sheet metal.

Thanks for any and all responses in advance

John
