I have just looked at the interior of the C6 and it will present some problems for C6 owners who intend to install a Harness Bar.
The B Pillar attatchment points and the shoulder strap reel are hidden behind the B Pillar plastic surround (enclosure) and not readily available as in the C5.
I have also talked to Gary Hoffman at Hardbar and have seen their C6 Prototype Harness Bar installed. It took some engineering but they got it done.
Gary still needs to take some final measurements for the production model and needs a C6 owner in the NE to come forth. The reward will be a FREE new harness bar.
So if you live in the NE and have a C6 and need a Harness Bar and wouldn't mind being a test mule , email me
