Non stage 1 auto trans GS 455 car in 70 was a default 2.93 ratio as I recall. Confirm my memory plus it could have an optional raatio or it could have beem changed along the way. Reomve the cover and look on the side of the ring gear for the numbers that indicate the ratio.
thanks one thing when i jack up the rear it spins both tires and when i try to hold the driver side tire i cant? it wants to spino No: do you think it could be worn out the slon musem said my car came with some kind of tow package? what was that?
