Driveshaft Length Tolerance? (2002 Z06)
Does anyone know what the length tolerance is of the driveshaft (or driveshaft + driveshaft input shaft)?
The stock driveshaft + guibos is 42.5" long. I ordered a DSS guibo-less carbon shaft and installed it only to find the front input shaft torque tube bearing protruding from the torque tube. I removed it and measured the driveshaft to find that it was 42.75" long. After a couple angered phone discussions with DSS I now have a replacement in hand and it's 42 7/16" long.
Based on the pilot bearing wear on the input shaft it appears that 1/16" shorter won't be an issue as there is some pilot bearing contact surface to spare. However, it doesn't leave me warm and fuzzy installing something I know doesn't match the stock length.
Thanks all

So DSS says plus or minus 1/16." Based on two different input shafts I have and the OEM pilot bearing wear marks on them, I agree that 1/16" either way is acceptable.

i would rather have it be 1/16'' less and have that bit of free play then to have it be 1/16'' to tight and have it fitting to tight
