You need to get the long variety baloons. You also need a piece of brass tubing that the shock coils can slide over.blow in one end of the tube and slide the baloon on the tubing. Then roll the baloon up like a rubber, but not all the way off the tubing. Slide the coil over the end you blew into until it's up against the rolled up baloon. while compressing the coil, unroll the baloon over the coil. Once it's covered, blow in the open end of the tube and slide the baloon covered coil off the tube. Now take the coil, and slightly inflate the baloon, but keep the coil strait in the baloon. This will unload the coil and get it postioned in the baloon better. Try to get the far end of the coil right at the closed end of the baloon. Then slowly let the air out of the baloon. Once this is done, cut the open end of the baloon off about 3/8th inch from the end of the coil and fold inside the coil. This will be the top side of the coil, and the plastic thingy will keep the baloon in place. On the bottom end, cut a slit in the baloon. When you install the coil, carefully shove the shock end through the slit. This will help keep dirt from getting sucked up into the coil and onto the shaft.
The baloons are easier to clean than a cloth cover. Windex, 409, and even nitro cleaner (in moderation) will not harm the baloons. I used a set on my savage for nearly 6 months before I had to change them. Check my gallery for pix of what they look like.
Somewhere, I have a how to page with pix, but I'll have to go digging to find it. If there's any questions, I'll be happy to try and help out.
EDIT-- Now ya tell me. lol. I needed another post anyway. :spam I am.
