They called me back to say they went through all of their documentation and can't find anything that matches my existing strip sizes, so they can't sell me a wood kit.
While I am disappointed that they have a listing for a kit they can't actually produce, I respect them for going through the trouble to check and verify my needs before taking my money.
I still believe that my wood is original and correct due to other 58/59 trucks I have seen in person and online. Also because there are not extra holes in my cross-plates that would indicate it was redrilled for different widths.
I would still be willing to do business with them, but I would call and verify their offerings rather than just ordering online.
