I replaced all my glass back in 2008/2009. Side windows are really easy compared to the windscreen. But that can be all relative too. Check out the link below as there is some posts about the project and contains info on the side window change. Great Lakes Aero Products are a first class supplier and I highly suggest them for your supplies. They can be found on-line and have pricing listed for your plane. Any other questions let me know
