The area you put lightening holes in the chassis below the door


Yes, I would like to see the failure point as well.

The holes are actually NOT for lightening (although that is a nice sideeffect) - once the holes have been flared/swaged they stiffen the plate up considerable, that was the reason the factory did it, and the reason I did it too (and for looks ofcourse).

The weak point of the chassis is the lower B-post area. I would assume this would be the area Jerry is referring too. This area is often (almost always) rusty on Panteras that has seen real world driving and rust in this area will weaken the chassis considerable.

I my car I reinforced this area (if you go waaaay back in this thread you can see how) AND the roll cage will support this part of the chassis somewhat more. In addition I seamwelded the seams between the inner and center rocker a long the entire length.

BUT, by no Means a pantera is a safe car :-(.


When Hall was building the "T-top" car and trying to stiffen the chassis enough to make the roof panels not squeak, he inserted at first a roll cage tube, then a lightened extrusion through the rocker panels on each side.

They bolted to the inner fender wells and the bottom of the roll bar.
