Need Help with 88 Trofeo Door Lock Cylinders

[Our88]

Hello - newbie to this forum, and have not been able to find reference to my issue here yet. I'm counting on the wisdom of the members.
This is my father-in-laws 88 Trofeo that he bought new in late 87, and will stay in the family for a while. We just got the Historic Vehicle plates
We started the summer with frozen/seized door lock cylinders. After a couple rounds with PB Blaster I gave in to corrosion. I researched Rock Auto, Summit Racing, and other sites I have used in the past and saw every part looked the same. Ordered a set hoping for a quick replacement.
When I pulled the old ones out, I knew I had a challenge. Ours have a long (approx 1/2") shaft, with a wire crimped to the base of the bezel, and the replacements are short shaft (3/16"). I am assuming that ours are special for power locks, or some feature I haven't discovered yet.
Has anyone had this experience, and are there any recommendations for sourcing replacements (NOS, salvage, other)?
Any other recommendations or solutions?
Thanks in advance.

Thanks for the resource. Still building my list of salvage and part resources, so I appreciate the help.
