Default EGR Solenoid Replacement

Hello, I have a 1981 Corvette with all of the emissions equipment still installed. I was replacing vacuum lines and found that the top EGR solenoid on of the pair had a broken inlet that had been glued together previously. I would like to replace both of these the lower can be replaced with a EGR solenoid valve from a 92 and I found instructions for that, but what about the upper? Can anyone tell me part numbers for anything currently in stock that I can use? You can see the two I am talking about below. Thanks for any help you can offer!

I believe the lower one was 1997518 and the upper one was 1997517 which number changed to 1997536

I don't have any history on 1997518 but what I do know is that both fit Pontiac and Oldsmobile cars as well.

Thank you for the information. I can't find the 1997518 part anywhere either. Do you know if the top one is for canister purge?
