Protex catch help..

[gotchiguy]

Want to swap our "lockable" Protex catches for the same ones we have at the rear which have little sliders.

However, they have slightly different screw patterns, the slide ones we have have the screws outside the body and the lockable ones have it just behind the lock barrel.

Will these have the same crew pattern as the outgoing lockable ones do you think? I suppose it wouldn't be a disaster if new holes had to be drilled but I'd prefer to keep that to a minimum. Pic attached

The drawings are on the Protex site, you should be able to compare the two.
