Here are some dimensions that may help you source them:

Spring ID: ~15mm

Uncompressed Length of 1 Spring: ~85mm

Uncompressed Length of Combined 1.5 Springs: ~130mm

The approximate 130mm length yields approximate full spring compression, also known as fully "stacked", when the hatch is closed.

The ~15mm ID may need some persuasion to thread over the ball end of the hatch strut. Consider wearing gloves and safety glasses during this installation process.

Your results may vary.
