Oh now that makes sense -very good --Thank you very much---I'm doing A ground up resto on our GTC and as I go I'm changing everything I can to Type 1 --I even put in A stock brake master cylinder -- A type 1 new swingarm trans-- and as I go making it all Type 1---- so that it will make it easy to change out stuff in the future. Thank You again Harvey
