Rain Drip edge on a 1970 4905

[johnjem]

Can any one tell me that has a 1970 4905. I am looking for the location of the rivets on the rain gutter , I seem to have covered them up and lost my paper work as to where to find them,when its was time to reinstall!!!   Looking for measurement  from edge of roof line to the top of gutter  or to the rivets !   Any help would be great !! Don't want to be drilling around to find the original pop rivets holes!!  Thanks john
