Chances are better than 50/50 in my experience
Get them to measure the overall length of the cylinder and compare that to yours. Too long is okay, usually, as you can shorten the cylinder bushing with a bit of filing. Ruger's barrel/cylinder gaps are usually generous enough to allow a longer cylinder to fit. Much too short and you get bad endshake.
