Chaparral rifles parts interchangeability

Question: anybody knows if a Chaparral 1873 rifle will use the same parts as a real Winchester 1873?
I've heard they are built exactly like the originals, but ain't found any evidence of parts' interchangeability?
Thanks!

I honestly have not used and will not work on Chapparal guns - their quality is not up to Uberti, as an example and some of their parts are much softer than Uberti and tend to wear. BUT, I have heard repeatedly that they are not 100% interchangeable. I don't believe they use the same firing pin system and I believe the link pins are not the same diameter as an original. This is certainly true of all the other Italian clones as well.
