Acorn 2" Window Tilt Latch Replacement

I'd like to find a replacement (2) for this Acorn 2" Window Tilt Latch. The depth of the current Acorn latch is just under 1", which includes the lever. The depth of the window sash itself is only 1", making the current latch very difficult for me to operate.

I assume the current latch is made of vinyl. I will be having my handyman install the replacements. I would prefer that screws of the replacement latches fit in the current screw holes, which are 2" from the end of the latch to the center of the screw hole. (I suppose that's what the 2" measurement in on the name of the latch indicates.)
