Change out an F1 to a manual shift set up? F355

Do you wonder about its history, or present disposition?. It lived in Alaska for a while , it sold at auction, twice. At the second auction it got its salvage title. Its likely a Katrina casualty. The salavge was due to flood. Was it fresh water or salt water? Unfortunately it was salt water. Did it go up to the dashboard i asked? Yes it did. It now has electrical problems that are unresolved after over $10k in used parts, wire harness, conectors, ecu's, sending units, etc. The seller paid $50k and approx another $15k in service and parts. He seems to be stuck at not selling it for under $35k, can't say I blame him, not sure I want to trade places though....Leslie.
