ISO: Expert on Dura Ace 7500 or Pitch 10. Headset info needed.
trying to see if the crown race (aka base plate) of HP7500 (Track Headset in 7500 Group, mostly only sold in J in 80's for Keirin) is interchangeable with other DA models i.e) 7400 or 7410.
it's also the same headset came in the infamous DA Pitch 10 Group. if anyone with the link to 7500 or Pitch 10 spec sheets, it'd be helpful too—they are almost unobtanium.
long story short, found one in JIS crown race, but i have an ISO fork. gonna buy if i can source compatible crown race.
*pls don't tell me:
1. to use other headset. i need this specific model for my build
2. to google, cuz i've done quite a deep search. if you know, in fact about 7500 or Pitch 10, you know how hard it is to source one.
3. to use a shim. it's the last resort. would like to get an info first.

This is something I really truly want to help with but am not certain. My gut feeling is yes but haven't a thing to back it up however I might give it a try.
I do really desperately want to see this build. Please post pics
