    Thunderbolt IV ==> Thunderbolt V?

    So I'm wasting my Sat. afternoon time pipe dreaming, and probably will be wasting some of your time too. I'm wondering if my '96 4.3LX could be converted from it's Thunderbolt IV to a V. Assuming the graybeards don't answer "Nope", I have questions. First mine is working fine, and hopefully...

    On behalf of my penny-wise, pound-foolish boating bud. His old roller arm cut-out switch is bad, and he shifts w/o the cut-out function because he is too cheap the buy the $116 807962A15 riveted old switch/plate assy.
