My car has an 11/70 build date and it came with a wheel choke. For some reason, the prices for used ones (and new ones for that matter) are absolutely outrageous. Every so often they come up on eBay at a decent price. Just be sure it has the threaded stem and wing nut to be able to attached to forked receptacle on the spare tire pillar. Also since so many trunks have rust issue be sure it’s a solid one.
