ive heard that the 65 val front wheel opening is close to the wagon rear opening

Yes, I am the one who posted that here. It will work, but it will need to be shortened slightly by maybe 3/4 inch. I figured this out because both quarters on my wagon are FULL of bondo. I already have the drivers side cut out and I have a right front '65 Valiant fender which has been held in place to see if it would work. If you put it in the right place it even has the lower body line which will line up... Unfortunately I am deployed and cannot get any pics for you. It is a lot of work but not as much as fabricating a wheel well from scratch! If you find a pic of the valiant fender and compare it to the wagon wheelwell you will find it looks almost identical... Good luck
