3 on the tree to 3 on the floor conversion

looks like a different plate - only 3 speeds metal . 4 speed is aluminum with 3 allen inset screws
easily obtained from Passion or Brewers

Thanks for the lead on Brewers. Talked to a friendly gentleman there and he dug one up from a pile of 3 speed parts he had in the back. Another missing piece to the puzzle has been found.
