The previous owner put on the wrong wheel nut and I can't find the right nuts anywhere. It's a 14" rim, the nut size is 7/16 and I'm pretty sure it's supposed to have a shank, larger head and washers.

The guy at the local parts store said they're rare, and $20/nut.

Is there a cheaper alternative nut? or just general size specs I could follow?
or is it worth it to get new rims?

Any info or advice is appreciated
thanks

Yes, buy new wheels and tires......
