Finding parts for Olds 88 Basic Sedan 1956
 

Trying to find a 1954-1956 Oldsmobile NOS Heater Fan High Low Speed Resister Block GM #3131533. Use in both Buick, Pontiac and Chevy in none AC cars too?
Also, looking for the brackets for a front seat to mount the seat to the floor? I owe a 1956 Olds 88 Basic with 324 Rocket Engine 4 barrel carb. it is 90% restored? It has the original two tone paint gray and blue paint, with tan leather interior. I live in Great Falls, Mt, and I am retired sales rep for Autotrader.com and Cars.com.

Any help would be appreciated?
