Awning Window Operator

good day,
my operator is similar to this one below. the good one is still riveted on the drag link. my dimension across the bottom two holes is 1-5/16 cl-cl, and top to bottom on the mounts is 5-1/4 the drag link is 2-7/16 cl-cl. pictures attached. is this the correct part? thank Rick.

i must have changed one of these out with a non standard part. the one shown, one of the originals, has the bottom mount holes 1" apart. the upper to lower is still 5-1/4 but the drag link is 2-3/4 cl-cl. the upper hole is offset what appears to be about 1/4". inside the cavity i can see "11500-3" and "1 R.H.".

any help would be appreciated.

thanks
Rick

looks like top to bottom is actually 5-1/8. and this is the part.

thanks
