The only parts that need the metric thread are the threaded cup and the locknut, and those seldom wear out (the lower race takes all the load; the upper race is just for alignment). If you have the original threaded parts, keep those, and just replace the lower stack with new components of similar stack height.

I have just bought a Motobécane branded headset (apparently made by Stronglight for them) from a seller in France. He measured it for me and told me it was 35mm stack height. Well when it arrives I will let you know if it fits.
I noticed someone on eBay in the USA selling one (mtr0089 in Neeah, Wisconsin) but import charges made me look to Europe (though I get charged more after dammed Brexit). It was on for $79.99 but watching it they gave me an offer of $24…..
Well hopefully that is one problem down, now just having to drill out the adjusting screw in the drop out, I hate doing that….

Total stack height 26.42 + 11.38 = 37.80mm. This is without any compression from tightening with bearing inside. The total was included so you could see the depth inside, if you wanted it….
Is that a nice postage stamp or what?

But (someone always said anything before the word but was HS…lol), the bottom crown race. I took a gamble and it was 26.5mm not the 27mm of my fork…sigh you can’t win them all with French bikes, that’s why I love ‘em! I will just get the race skimmed 0.5mm internally. Just so your ready….!
