O.K. so I'm a little dumb on this one. I have the three bars that hold the front air-dam on a 68 Camaro, and its quite clear where the shorter ones go. But where does the long one mount on the car itself? I tried lining it up with anything it could reach and it is not clear to me where it goes.

It is necessary to drill a hole in the frame bar that connects the front beam and the beam under the engine. This is the correct way. There are no provisions from the factory since 67 and 68's never had front spoilers and 69 frames were the same as 68's.

67'S and 68'S did have spoilers from the factory. 67's and at least early 68's didn't use the center bar support. The spoiler just hung there. Later model 68's and all 69's got the center brace, although there are two different lengths used. a shorter bar for the 68's and then the longer one for 69's. The hole for the spoiler was drilled at the factory, it's location and diameter is clearly identified in the assembly manuals. A self tapping screw was used to hold the brace to the center horn of the subframe.

The subframe is not the same from from year to year. While they will all interchange there are numerous differences between the different years. Most differences are in the location of the lower control arm bump stops, that are welded to the frame, and the bracketry where the sway bars connect to the frame.

Thanks to both of you. The info was very helpful.

You're right Mark. The 67 68, did have front spoilers, my mistake. The 68 and 69 frames are the same even though they used the slightly different anti-sway bar frame bushing design.
