Default Phase Linear 4000 Series I Transistors

I was trying to find two different transistors I need to build the Logic board (PL04.)
Does any member have or know where I might find FPN3569 and FPN4355?
I cannot seem to find any info online.

I believe I have an answer!
I just dropped the FPN prefix and found them listed.

The "FP" part is probably a phase linear custom marking while the devices themselves are just regular 2Nxxxx devices, remarked "FPNxxxx" and sold at 10x the price.
