Ok I need some help, I hear alot of people say just use "spacers" I want to switch rears in my car but I have a mono leaf setup now but the rear I want to use is set for multi leaf now everyone says its OK just use spacers, ok where do I find these "spacers" and is this really safe to do? wont the rear tend to move a bit? has anyone done this? If so hows it work? do you ever have movment? thanks for your help!

well, lets see... the most important thing is to positively locate the rear axle, both side to side and front to back. All springs have a center bolt of some sort, that's how you locate the axle. Best is if it locks in both top and bottom, but just one will do.

Then you just fill the space. My previous setup had multi springs in mono perches. The springs locked in to the preches and plates just like they should, I just needed to fill the space between the plates and the perches caused by the thicker spring. A trip to home depot for some 1" x 1/4" aluminum bar stock, cut to length, drill holes for u-bolts, stack to fit. I chose to keep the rubber pads, so it was quite a thick stack.

My current setup has multi springs in multi perches, but I deleted the pads, wanted solid mounting. I also wanted to lower the rear of the car a bit. I bought some 1" lowering block from summit. They are made with a locating nub and a locating hole. It took a lil massaging to make em lock in good, but they do. The spring plus the lowering block added up to a thicker stack than the spring plus the rubbers, so I still needed to use a few spacers between the perch and the plate, but you can bet it is VERY solid, it's not going anywhere.

For your application, I'd let the springs lock into only the bottom plates, and make a spacer for on top of the spring, either by bandsawing a lowering block to the height you need, or using multiple thinner plates, or taking tth full inch drop and making up some perch to plate spacers.
