Hello Paul,
I can see that a spreader would work..BUT also did you have any luck ID the parts that I need. The pictures include the stop and the coil, or is it best for me to remove one and try to photo and try to get some measurments?
Yes; unfortunately, we will need to see these parts removed from the window in order to successfully identify them. Please also provide measurements, and tell us of any numbers printed or stamped on the parts themselves. Thank you.
