Beetle tow bar

Hi - wondering if anyone can help me out. I'm looking for a tow bar that clips onto the lower torsion bar of an older beetle ('58 in this case).

Specifically, I'm looking in the GTA (Toronto, ON) area. I know Johns Bug Shop in Welland stocks them but, he's on vacation this week and I need one sooner than next week.

Any help would be appreciated.

Thanks
