If you near Clifton NJ,.....Driveline Service can cut weld balance your shaft, bring the yoke if you want them to assemble the whole shabang 973-473-7900,....depending on your location, they may have another shop closer,....I just measured the BB 70 Cuda 727 8 3/4 shaft I have, it's 43 3/4" ctr to ctr on the u-joint eyes,....no it's not for sale
