I like them both. Mine is a 73 with the correct rear spoiler that has the bulky looking end pieces. Since mine isnt a #s matching resto, I was thinking of changing to the later spoiler which gets rid of the extra plastic to make room for the wrap around lights. That, or change to the 70 style because its cleaner. Yours and the Greening piece look like great alternatives to me. And I agree with above, its your car, dont style it for anyone else.
