Installed left and right side baggage area supports. Also installed bulkhead including support for rear baggage skin. Have not installed rear channel frame supports and "Z" supports for baggage skin. This part of the construction is going slower since there are not any photo assembly manual instructions covering thiis area. Photo assembly instructions are for 601 which is different from 650, The concept is the same but 650 instructions woiuld be benefical. Will need to calll Zenith for clarificaion on some the plan drawings whcih show conflicting information.
