A '70 is similar, but not the same.
The marker light hole is bigger on a '70, as well as the ''L'' shaped bracket on the '70 (and '71) is spot welded towards the front of the fender on the inside near the front to mount the long hood latch brace/bracket that is not present on a '69 Valiant.
Here's a a few pictures of a '71 Scamp and a '69 Valiant for comparison.
Yes, these are my cars........
You can use one from 67 to 76, just have to do some small changes. side light, head light bucket area and the brace if it has it. No big deal. All worth it for a mint fender at the right price.
