I recommend getting the piece called the spring bumper or bumper back on Carson's site. The front ones do get rotted out and were so on mine. In addition, if you want the lower insulator or insulator back on Carson's site. However, I will show you a different idea on the latter, something I have presented before.
Now, I wanted to make note of something first. On the driver's side you will need to remove the 10 mm bolt holding the brake fluid reservoir if you want to get at one of the 14 mm bolts on top. The end of my finger is where the 10 mm bolt is.
Well, that is exactly what we did for the other 3 springs as well.
Each individual spring needs at least 22 inches (yes, I am not kidding you, it does not look that long, when you wind it around it is) to get to the point shown in the preceding photograph.
The width of the hose is about 2 cm or .75 inches. The rear springs can use a slightly smaller width, but I recommend using the same width as the ones up front. Note, I am slightly squeezing the hoses in the last 2 pictures.
This type of hose can be found at Home Depot, though in downtown Cuajimalpa where we are at, such colored hose is abundant at small hardware stores.
