I am going to do take-offs on the female (part the jackscrew rotates in to engage the window regulator.) jackscrew today. Hopefully looking to have some machined from quality steel. If there is any other interest in this part please let me know
See Snyder's A-47832-N, on page 206 of newest catalog.$12.95 will work fine and save you much time.
Nice to know and will give it a try. Most thanks.
