Same as CZ 550? Sources?

I have a 601 in 308 that is not hanging on to its cartridges. Out of the rifle, cartridges are very loose compared to my 602.
 
A 550 extractor will fit but will be half an inch too long because they do not make a 601 equivalent, only a 600 and 602 length

Unless someone has permanently altered the hook, any gunsmith should be able to adjust it to the correct tension.

Likely the collar ears are bent or twisted and reducing the tension. Any 98 collar will work

I don't think there is anything wrong with the collar. The extractor sits nice and tight all the way down. If I hold a square against the side of the bolt and across the outer surface of the extractor, I see that it is not parallel to the bolt face (it's pulling away). I don't know if this is a telling feature, but my 602 is not like that. Regardless, if I tried to knock it back into shape I'm sure it would break - hence my search for a replacement.
 
Would someone tell me what I'm missing here:

I took an extractor off of a Husqvarna 640 (FN made model 98) and slipped it onto the BRNO bolt body. It's 1/4" shorter than the BRNO, but it cycles fine.
