Posted February 15, 200223 yr comment_3114 I have a '73 240z and was wondering if 240 and 280 locking gas caps are interchangeable? The locking gas cap i have now won't unlock anymore.

March 11, 200223 yr comment_3804 No, the caps will not interchange. The 240Z to early 260Z (thin bumper) will interchange. The later 260Z (thick bumper) and 280Z will interchange. The hole opening on the 280Z model is smaller then on the 240Z model. Has to do with going to unlead gas and pollution controls of that time period. Sorry, Rich.
