Default Check Engine Light -Code 75,76 78

I have a 97 SC400 with 65,000 miles and my check engine light lit up. Went to Autozone and used their tool and it read 3 codes. Code 75,76 and 77 (EGR solenoid failure 1,2 & 3).

Should I go to the Lexus dealer and ask for these parts or is there some other trick to fixing them?

Thank you in advance for your help, John

those numbers sound like obd-1 codes... obd2 codes are typically formatted pXXXX (by the model year car, it is obd2)
