1970s Rough idle

[shadetree39]

Rough idle check per manual suggests cleaning injectors. Pictured are seal purchased from 2 sights. The current injectors were installed new in 2004 by Heritage Cadillac in Lombard,IL and driven but 900 miles since.
Compression, vacuum , fuel pressure spark plugs read fine. No fuel leaks so I'm afraid to remove them and not be able to reassemble successfully.
Can any of the proper seals from pic?
Shown also is a nos 5720a 740 I got with the car for 76 Eldo. And that is what is in car now.
I have the set I was told that were removed but the part no is 1181347. They are quite different.
Anyone have sources for seals?

There was a thread not all that long ago, like the last couple years where someone else was asking the same question and our EFI experts got involved possible with others and kinda sorted all this out.  They had come up with a bunch of details on what to look for in the ads and then what to look for when you get them to make sure you had the right stuff.   I do remember there were more wrong than right out there at the time. 

Anyone remember enough details of that thread to search for and find it?  I just tried a couple terms and got way too many hits and a quick scan through those I didn't see the one I was thinking of.

I just did another quick search and could not find the thread I was thinking of.  One thing to note is it looks like with the forum membership rule change last year we lost a couple of the people that were pretty active and developing replacement parts for these systems.  Hopefully Bruce Roe is still with us, he hasn't been online for almost a month now.
