Hi, I have just fully restored a 1969 F250 390 styleside longbed Truck and
I wish to put a tonneau on it. No one seems to be able to tell me if my 1969 is the same box size as a 1973 which "Truxedo" have listed tonneau covers for.
Can any one tell me the box size of a 1973 longbed F series.

My 1969 box size are:
L - 96 7/8"
W - (at cab) 64 7/8"
W - ( at tailgate) 65 1/16"

Thanks - Peter - fgtcars
