2.6 is what you found.

thats basically gonna point at 2.73...

sometimes when youre counting rotations you end up needing to double what you find, depending on how you did it

one wheel on ground or both off ground.

will change what number rotations you get.

doing it with one wheel on the ground will be most acurate and easiest...

note: 2.21 and 2.56 were available and uncommon ratios in these trucks as well over the years, after 1972 when the awesome CST generation of trucks ended.....

not as common ratios as others such as the 2.73 and 3.07 and such....

GM had alot fo oddball ratios in the trucks....

2.56 and 3.40 were a couple of the least common ones....

2.21 was another uncommon truck ratio too actually.. i forgot about that one almost... ive only seen one or two actual 2.21 trucks ever in my life, listed on the RPO sticker and all...
