Be careful, these lowering blocks may not fit your car.
It was great to find lowering blocks in this many different sizes so I could get the perfect ride height for my car. The problem is that these blocks are straight extrusions with no taper and the spring perches on my 1967 Camaro are tapered, so they did not come close to fitting on the car. I had to have them machined to fit, which is the first time I have ever had to do this with any other lowering block. I was very disappointed with this purchase, because of the time it took to get them to fit correctly.

Used with mono-leaf on 1967 Camaro. Had to reduce size (diameter) of tab on bottom to fit into hole on top of leaf spring. Once that was done, seemed to work fine.
