pins for Marvin infinity window screen installed 2007

A home owner from Pennslyvania says:
I have Marvin infinity windows installed in 2007. The plastic pins holding the screen are becoming brittle and breaking off. They are translucent white plastic with a spring. About 42 mm in length with the end piece pushed in. The diameter of the smaller end is around 3 mm.

Some Marvin windows have use dour 70-219 Plunger Pin assemblies in the past. Look over the dimensions listed in the pictures on the shop page, and let me know if you think these match what you need.
