The dates are the one on the right is a 1973 and the one on the left is a 1974. I have had a few of these in girls bikes and have always wanted a mens bike, becase they ride so nice. I found the second one by riding the first one. I was test driving the first and ended up at another garage sale. The guy there looked at the bike and said he had one just like it in the back yard. so I bought it. They were 20 bucks each, 4 times more than i usually spend on garage sale bikes, but it was worth it.
