@ pop23235;
I believe you are correct. I looked in the 64 AIM and can not find the sw p/n for powerglide [M35] and b/u lts [T86]? 63 & 64 use the same neutral safe sw 1993617. Did find the note in the 63 AIM [T86] that calls calls for sw p/n 1993637 for pg trans M35 and b/u lts, T86. I am sure this is clear as muddy water.
I "believe" your sw is p/n 1993637, rare item indeed. Who restores these?
Aloha,
Rene'
PS, found the note in the 64 AIM, same switch p/n.
