Some differences between a 170 and 770 are, more chrome/stainless trim on a 770 and the upholstery patterns are different also. I'm sure there are other little things too.
You found a nice Lancer! I like the red wall tires! I have had my Lancer for sale for a while, but I am having second thoughts about selling it. Nice find.
I live in the North East part of M.A. The Merrimac Valley area. Will try to get a pic of 74 road runner in the gallery even though it is a B body. I hope that I don't get in trouble ! I can't for some reason post it here. I did post pics of my Dart Sport in gallery.
