Need Replacement Part Identification Help

Hey there!

Thanks for reaching out to us. The 15-251 comes to mind. This is designed to use the Series 160 coil springs which are sold separately. Take a look at the specifications and see what you think. 

Thank you for the additional photos. The 15-251 single support is the closest option we have for what you show here. We sell the 16-033 mounting bracket separately but you can reuse the old one if it's still in good shape.
