Yes, tater made me one with chromolly using the mounts from the stock unit and lowered 2 inches and extended 6. I am running it on my drag bike now and it works perfect. Check out my build thread "ducktape and spraypaint" there are a few pics of it there.
I am going to be getting one of these long travel swingarms in the near future for my trail bike.
Excelent work tater!!
