Modifying '69BB fan shroud: Plastic rework

[69427]

I'm making a few tweaks to my fan shroud to clear the new A-arms and the rack plumbing. That's been easy so far, with just a couple of quick jigsaw cuts. However, I need to make a major change to make a full width (approx 24 inches by 2 inches) notch in the bottom of the shroud to clear the sway bar, which is positioned a couple inches above the stock location. Essentially I need to find something to make a half round clearance bulge, but also have a way to glue/rivet the half round bulge. Riveting would be easy, but are there some plastic/ABS/PVC options? Would epoxying or fiberglassing be the best? Additionally. what plastic sheet material would be the best to later rework/seal up the areas I had to cut away for suspension clearance?

thanks,
Mike

Years ago there was some plastic we used in the company, called KYDEX soemthing similar spelling.....it was a black plastic we molded and formed to what we needed, simple for us even WE couldn't fuck it up.....I don't recall any glues needed though for our work....

but as I recall the material charactoristics were very similar to stock plastic fan shrouds....

IMO, do Dual Spals....DeWitt or Ebay....

Additional (up front) weight and complexity.

Glass/epoxy would be your best bet. Most sheet material (like ABS and PVC) will get pretty soft around a radiator.

Anybody know what the shroud material is?

The fan shroud from my 68 was made by General Tire (or some other tire company). Not sayin' it was made out of rubber but I wouldn't be surprised.

I think Doc Rebuild sells materials that are used to repair stuff like heater boxes. Maybe he sells repair materials for fan shrouds?
