'68 and '70 are not the same. In '69 they got bigger in diameter to meet federal regulations. Cruisertom, measure the diameter of your lights. If they are the big ones, maybe speedn3 wants them, if they are the small ones, I might.
Where are you located, I have a set off my 71 , They are in good shape other than one has a bent flange around the bottom.
I would take $15.00 +shipping, If you want some pic's give me a day to take some.
