Hello,

Your pivot shoe resembles the 15-111, which is commonly used with the S160 coil springs. You'll need to remove the original coils to determine how many you need and locate the numbers on them to choose the corresponding strength options. Thanks for posting!

Your coil springs resemble the 3/8" wide S165-5 replacements.

As for the tilt latches, take a look and compare the specifications of the 26-390 and 26-391 latches to yours.
