I think I read on another thread that someone didn't use one of the perch pads, but this doesn't seem like the best thing to do. Did you put the spacers between the spring and the pad or between the pad and the mount? Would it matter?
I think you have the wrong idea about the spacers. Once you have the 3-leaf in the upper perch you will begin to bolt on the bottom perch. The leaf spring and rubber pads will all be sandwiched tightly between the upper and lower perch. There will be no need for a spacer because everything will be compressed tightly together when you torque the bolts holding it all together. The place where I made spacers was on the sides of the perches. These sides used to contact each other with the mono leaf in there, but the extra 2 leafs that you will be putting in there will prevent them from doing so. Like I said before, I think most guys just torque them down tight and just run them as is. Maybe that's all that's needed but I decided to make something to give a little extra support.
Picture two flat pieces of plate steel sandwiched around a leaf spring. Then imagine putting four bolts at the corners thru the plates to hold it all together. If the plates weren't strong enough, they would bend in toward each other as you applied torque to the bolts. You could prevent them from bending if you put some spacers around the bolts between the two steel plates. This was the concept of the perches with the mono's installed, that is, the sides of the perchs bottomed out against each other so the perches would not bend. When you install a spring that has two extra leafs, that added height, will prevent the wrap- around sides of the perches from reaching each other because they were designed to only reach around a single leaf, not 3. Now I'm not saying that the perches aren't strong enough to hold up on their own, I really don't know for sure, it was just my preference to support them with my homemade spacers.
