So the fenders were junk on my 72’, and I was able to source a pair of real nice 73’ fenders cheap. I was aware of the 73’ fenders needed to be notched for the 72’ bumper so I marked them out based on the dimensions of the original fenders. Problem is I left them out in the weather too long and my marks are gone, as are the original fenders. I did a search and while there is info, I couldn’t see any posts with the notch dimensions. Can anyone help with those dimensions?
Maybe this will help. Check out Fender Notch. Don't know about a '73 Fender but the '74 fender is different around the headlight than the 70-72. On a side note...the 75 fender is also different than the '74 fender behind the headlight including the bucket.
the 73 fenders I notched appeared identical to the 72 fender I used as a pattern, except the 73 weren't notched.
