So I bought these kits off a guy on Ebay for 3 of my bikes. I got a quantity deal and saved on shipping. They are broke down kits you make fit whatever you have for a bike. Here is a pic of the axle plates on and with the top rails.
Then I cut the bottom rails to fit and it started looking like a hardtail.
I still have to finish welding and add some gussets to support the rails where they meet the original frame. But I really wanted to see what it's going to look like with the seat, fender and sissybar so I mocked it up for this pic. (the blanket under the seat is there to put it about where it should sit)
