Thanks for posting. Please take a look at our 15-180 pivot shoe, 15-181 coil spring housing, and 15-182 bushing. For the coil spring itself, check out our Series 190 and see if that matches.

The 15-180 coil balance shoe appears to be correct, but the plastic composite parts all seem to be in relatively good condition. There are a 640 coil and a 540 coil on each side. Only the 640 coils are broken, but I want to replace all four of them. There is a flexible weather stop that sits atop the support detent clip missing on one side. It measures 1-1/4" x 17/32" x 1/4". Do you offer that part? If not, any suggestions? What would you suggest to lubricate the parts, if anything?

Great, thanks for the information. With those numbers in mind, I can specifically recommend our S190-640 and S190-540 coil springs.

We don't have that rubber bumper, but we do have a few things that might work for you with some trimming on your part. Look at our 15-148, 80-002 and 21-276. For lubrication, you can use a silicone spray. I don't recommend oil, since it will collect dirt.
