cylinder stop on k frame

[chris66]

hello, I need to replace the cylinder stop on a pre model 10, it's a 4 screw (no screw at very top of side plate). ebay has all kinds but they don't specify if it fits a 3 screw or a 4 screw. Is there a difference? can a 3 screw cylinder stop replace a 4 screw cylinder stop without modifications? numrich has mim parts and I don't want that. Thanks!

They are not the same.

The 3-screw stop has a hole milled for the cylinder stop spring.

thanks frailer, so a 3 screw one wouldn't work in mine?
