Well, hold on a minute....
OK, maybe I am just too picky to be healthy.* Been looking at the photos I took yesterday, and REALLY looked at things closely.
I asked the RPM about this, asking if this was a genuine GM replacement part and was told that the C5 torque tube input shafts are no longer available new, so the C6 input shafts are being machined down to fit the C5.
Well that is all and good and everything, but darn if it doesn't look like the area in front of the splines was worked over with a hand file.* And honestly, I'm not all that crazy about the stub that goes into the pilot bearing being polished rather than just left with the raw machining parts.
So let me ask you this. Would you put this input shaft in YOUR car?* Am I just being way too picky about this?* Or will this be perfectly OK?
