I have a second-hand Tamjets A4 Skyhawk which has seen better days. in particular the main fuselage formers have been butchered to fit an EDF unit and ducting. I want to revert to turbine operation and need to re instate the main formers and mounting rails. Can anyone supply scans or drawings of the two main fuselage bulkheads and the intermediate one half way down the fuselage?
