Having an issue seating my crown race

[Campy Rider]

I have a 1976 Gios Super Record and a new Campagnolo Record 1" threaded headset. I both cups installed in the frame, but the crown race refuses to seat. When it does it seats on crooked. no matter how much grease and work I put into getting this seated. I did notice that the frame is cut for a 26.4mm crown race, but the Campagnolo has an ID of 24.2mm I've never seen a 24.2mm crown race with that diameter. Aside from spending another $100 on a new headset, what are my options?

Just checking, no patronising intended.
You are hammering it on aren't you? It's not like modern headsets, where everything just slides on. The dedicated tool looks something like this

Yes I have a tool, not the Park, but I have one. And I've done quite a few of these and never had this much trouble.

24.2 id on the crown race sounds funny.
You could probably just find a campag 26.4 race and swap them.

I said the same thing, I'll post some photos when I get home.
Also I can't find just the Campy crown race without buying an entire new headset. It's the last model 2000's era 1" threaded headset.

Post a photo of the race, along with o.d. and I can look in the shop crown race drawer - another retrobiker may be able to help also.
