Can't identify mezzanine plug

44 pins (22/side) and .35 pitch

I have scoured the internet for what the manufacturer and model this connector is but I have come up empty handed at every turn. Looks like a Hirose DF40 but they don’t make one in the right pitch/pin

I need to make an extension to interface with this circuit and had originally tried to use the .4 pitch DF40 but it was slightly to large and won’t even fit cut down

Any help is appreciated

The only one that we carry that is smaller in size is part number 255-5302-ND

It has a 0.35mm pitch but a 0.6mm stack height.
