I can appreciate that you have (apparently) some sort of dealer access, however............
In the Renix world the 4.0 and 2.5 CPSs are the same.
#33004761 is an AMC/Renix/Siemens/Mopar original part.
Renix is Bendix is Siemens.
I'm not certain of the other part number, not all NOS or current Mopar is NOS OEM, this has been discussed here before-
In my 88 2.5 currently is an original Renix CPS, functioning properly for better than 30 years.
I have also played the NOS game, fun in the beginning but becomes a chore and a bore. Ultimately NOS will disappear.
As you point out only 18 33004761s available in the US and none overseas that I could find......I thought that Renault might have carried it over from other vehicles.
I currently have 2, Siemens, NOS OEM.
There will come a day when you will gladly pay for any part that actually works. Time is not on your side.
