1967-68 borg warner 3 speed reverse light switch

[jasonL78]

Ok searching for a needle in the hay stack for sure with this want. I am looking for a borg warner M13 heavy duty 3 speed reverse light switch. I have my original but it don't work and it is in rough shape. Since they only put 317 M13 transmissions in the 68 nova this may be a hard part to find. I think gm used this transmission in multiple cars in 67-68.
Any help would be appreciated.
