Wilkinson once had a Pantera arrive at his place with damaged a-arms. It was a concourse car and the tow company's insurance had to pay several thousand to fix it.
I think Wilkinson said there are openings on the square tubes that comprise the main support for the chassis, and those openings are intended for use when towing.
The photo below shows an opening that could be the one for towing. This is at the front car, in front of the a-arm and steering rack support.
My hunch is that the front a-arms are less susceptible to damage than the rears. I have seen a number of bent rear a-arms that may have been damaged when towed.
