I have an LTI 350 in my cruiser that used to be mated to a stock 3 speed and stock transfer case via a Downey 3 speed bell housing with a Downey Chevota clutch kit. I am now upgrading to a sm465/orion combo. the Chevota clutch kit is not that old and I am unsure if I need to replace it or if it will work with the sm465. Anyone have any input? I believe I am running the stock shift fork also- will that need upgraded?
