Wanted Pressure switches for 3rd & 4th gear 200R4 AC Delco 8683502, 8642473

[MN250R]

Hello, im looking to replace my TCC solenoid here this week. Since i was in there, i was going to replace the 3 and 4 gear pressure switch.
I see the 3RD gear was an AC delco 8683502, And 4th gear pressure witch was 8642473. They both seem to be out of stock everywhere including summit racing.
Anyone know where they can be found or a cross reference? Thanks!

I had one that was leaking. Used compressed air to test it and found out it was a gusher. Had to replace it with a good used oem piece as those switches are hard to find.
