I have a NOS front driver side fender apron for sale that will fit a 69 or 70 Mustang / Shelby. This part is in excellent condition. The part number is C9ZZ-16055-A. Price is $450 plus shipping. Email gandcmurphy@rogers.com if interested. Thanks.
Just saw these and if memory serves they must be 70 type, as 69 had a bulge for headlamp clearance and they were flat with no ribs...Just sayin' should still work just may not be a perfect replacement for a 69.

As far as the "ribs" in the those panels they were introduced after about mid way through the production year as an improvement. Took a while to use of the older version so we find a mix of both during production at Dearborn in 1969 and they being al used up by March from the data I've collected. For San Jose that year the change over was slightly later
