overdrive switch

[J Gentry]

Overdrive is broke inside of switch no way to repair it. Can not find replacement even at a salvage yard. Is there an after market switch that I can use to replace it? Any ideas appreciated.

I would think it can...have seen a guy who used a floor-mounted high-beam switch, which would lose the light in it. Wiring to the switch as follows from a 1992 book:
Term 6-20DB/WT to fuse #2 (5A) via splice back of dash
Term 1-18BK to Z1 ground splice
Term 3-20OR/WT to pin 10 on SBEC
Term 2-20BK/OR to pin 37 on SBEC
The switch is drawn that the indicator light runs off Term 2 and 6.
Unfortunately I don't have one to tell you which one engages, which locks out OD.
