Different size chainstays

I’m new to Cruzbike and very interested in buying a used vendetta. my inseam is 34” and my xseam is 46” could I get by with the standard length chain-stay or would I need a larger one. I know this seems like a dumb question but what are the different sizes and how do they affect performance. Lastly, if I need a larger chain-stay where can I order one. Any help from the forum would be greatly appreciated.
