Inconceivable to me that there is not a high-quality exact replacement available for the early switch from outside the automotive supply chain...

I haven't bothered to track one down as my Amazon is on only the second one IN IT'S LIFE,
And I have still have several NOS ones on the shelf, and a couple of the later setups as well.
Would be happy to send a switch/bracket, FOR FREE, with free shipping to whoever lives the furthest from northern New England.
State your case...
