I have tried the price searches many times,I find the price of gas,milk and postage stamps.The best I can find is to use todays prices and use the inflation calculator backwards.I have looked at thousands of vintage pictures,enlarging the pic to see signs posted in the windows.I have been researching this for months.If I use the inflation calculator,I come up with these prices
Oil filter change $3.49
Put on Snow tires $2.29
Shock Absorbers Special 4 for $13.99
Antifreeze Special $1.99
These prices sound close,anybody have some different prices? I want to be accurate on this.Thanks Terry
