A/C Heater Blower Switch Needed

[Gubernaculum]

1981 Regular cab 720.
Looking for the A/C Heater Blower Switch. 3 speed.
Mine lost high speed - other 2 speeds work fine.
Part #?
Only a dealer item?

Any help or advice will be appreciated.

Thanks in advance.

Found a USED switch on E bay for $79!!
Went to the Nisson dealer - there were 4 switches left in the system all in the antique warehouse in CA! Cost $54. Ordered one and received 4 days later.

Now all 3 speeds work fine - just in time for the summer weather.
