Pre-selector switch

I know that Stan Gilliland (Auburn Cord Parts in Wellington KS) sells the internals of the preselector switch (switch unit with wire loom) using more modern material (Delrin instead of backelite etc.). I have one unit installed in my car and it works o.k. Mario

Hello

I've traced a fault back to the pre-selector switch on my 812. However, I am unable to find out if there are any companys out there who can repair or replace this switch, can anyone help?
