Help ETA 7750 broken kif spring

[quantieme]

As you can see from the pic I have broken the kif spring on the balance I have looked on cousins and they have a pack of five springs but they say it is for lower jewel so is mine upper or lower cos I’m not sure and then they do a upper or lower Inca bloc and the picture shows a spring in it but is the spring in it or is it just the bloc and is it the right part for mine I just don’t know, this is an early movement 1987 and some of the parts are different from later ones as I found out when I ordered a 30 minute drive wheel and got a jewelled version when mine is pinned to the plate and you can just see it in the picture so that was £12 wasted,any help really appreciated.

thanks tony

I believe upper side is dial side and lower side is the one we see in the picture...

Are the ones that you're buying specifically for Valjoux because I believe that the incabloc springs or whatever they're called come in various dimensions...

No only worry will be fitting it, it looks like the regulator has to come off and that l am assuming is screwed from underneath the cock,
