found this in one of my old Sporttruck mags. Then i found it online. I love how much of a difference it makes in the pictures. I'm hoping to do this soon to my 69. I might try taking the inner fenders out to do a better job. right now just dreaming about it (down with a bad back). thought others might like a link to it.
