Rolled the Avanti out of the building today.

I need to replace the shackle box holes with a smooth contour, following the curves from the rest of the body.
The contour can be matched, but if glassed solid to the rest of the body, the frame can not be seperated from it, for it extends into the concave portion of the curve.
The Corvette makes this a seperate piece on their cars, just for that reason. A body repaiman helped a friend smooth the valence piece into the rest of the body, only to have to cut it out years later to do a body off restoration. Typically it follows a horizontal line hidden under the bumper and goes vertical at the exhaust tips, providing minimum line seperation.

The newer cars don't bother trying to blend, and just make an obvious piece for it.

1.I can shorten the frame to clear, but this will require a good bit of work, and will require new rear bumper brackets. But would rather have the original contours.
2. I can make a seperate valence piece like the Corvettes, cutting horizontal under the bumper. The vertical would have to be full length, since running sidepipes.
3.If I made a differentiated piece, it could be a stainless wire mesh screen enclosed with a small diameter tubing, perhaps 3/8". This could detract from the original lines of the car. Perhaps instead of making a wide piece, two small seperate pieces right where the two openings are.
Anyone have some good suggestions?
