Ok, my 1991 mustang has the 466/C6 combo in, now im ready to measure for the driveshaft length. I have the AOD yoke with the 8.8" rear flange on the driveshaft, my question is how much of a measurement difference is there between an AOD yoke and a C6 yoke, would it make the length different if i just measured with the AOD yoke on ?
