I have heard of mild steel and stainless steel for these torque boxes, but not fiberglass. I can see where you can get the appearance with fiberglass, but I am not sure that they would function as well. Link to comment Share on other sites More sharing options...
Jim78 Posted November 17, 2018 Report Share Posted November 17, 2018 Never heard of this before. Is it possible that someone laid up fiberglass over top of a bad pair of hog troughs? I would be very skeptical of this. The steel "body stiffeners" are an important structural element of the body. Do you have more detailed information about who and how?

mfg Posted November 17, 2018 Report Share Posted November 17, 2018 Fiberglass 'hog troughs' for Avantis were once offered for sale by an SDC vendor....and basically, they reinforced the upper fiberglass floor areas OK. The real issue here is there's no way the roll bar attachment point (riveted to a fiberglass trough) can be as strong as it would be if it were riveted to a steel trough. MORAL TO THIS STORY....................If you install fiberglass 'hog troughs' in your Avanti,....DON'T ROLL THE CAR OVER!!!! Link to comment Share on other sites More sharing options...

adamderosa Posted November 30, 2018 Report Share Posted November 30, 2018 I remember the fiberglass hog trough being sold in the 1990's, and on display at the International meet in South Bend. From what I recall they were well made and quite sturdy, and the vendor had his Avanti parked on top of a pair of them to demonstrate their strength. I think they had metal brackets within them for attaching the roll bar to the frame. Had I not replaced my hog troughs a few years prior to seeing these, I would've bought these instead.

Greg Giroux Posted January 12, 2019 Author Report Share Posted January 12, 2019 After inspecting the vehicle in person, the rusted frame at X member and side rails along with other issues, the hog troughs were the least of my concerns and took a pass on making an offer.

Smart move!.....When considering a purchase, a close inspection of these 35-55 year old automobiles is really a MUST! Link to comment Share on other sites More sharing options...
