People selling the reproduction 68-72 GTO core support should make buyers aware that besides the modifications necessary for a 68, that the support has to be totally reworked to fit.
The top plate and the bottom rail on the reproduction are parallel, on the OEM piece the support tilts 9-10 degrees forward with the bottom rail being horizontal and the top plate 9-10 degrees off horizontal. To fix this requires drilling the welds and removing the bottom rail and rewelding it to achieve the proper tilt of the core support. Rewelding requires additional metal to be added to fill the gap left at the bottom after positioning it correctly.
Image below is from the 69 assembly manual that shows the proper lean angle.
On the reproduction the bottom rail (point BD) and the top plate (point BC) are both exactly horizontal.
This is a major flaw and this item should not be sold without the buyer knowing it will require extensive work to fit properly.
