Do you have a Tape measure?
At a Bike Shop you might find Used QR skewers , for cheap..
When people break a wheel , the replacement wheel has a new skewer,

Much easier, if they can see what you have.
QR axles are hollow they only need to sit in the dropout,
not extend its length past the outside .
