Not 100% accurate, but it's the best I can do with digital calipers and a fillet gauge. Uses 6mm M2.5 screws but I don't know what kind of spring. For now, sticking in 2 pen springs will work. Sanding probably required.
The original spring has an outer diameter of 7.75 mm, a length of 26.5 mm, a wire diameter of 0.75 mm, and 12 coils. LMK if the proper name for the spring is found.
