My kid lost the gas cap from our '72 240Z and I need to buy a replacement. I want an OEM or OEM-like solution and should probably choose one with a chain (the old one didn't have one). 

I see the $97 option (needs a chain that costs $25) on Motorsport Auto and if I have to, I'll go that route. But does anybody know a better option?

Thanks!

Zcardepot is $122

Zeddsaver is $120-160 with the rings

there are some decent prices ones on Ebay

search for "240z gas cap"

BTW, count your blessings. My daughter wrecked one of my vehicles again this week and flattened it on the back of a 2015 Lincoln. It could be worse!

I referred your post to one of our fellow members who may have one available.

I have a set available.  See:
