The lowers have different bushings so you need to know the year of the subframe. The bushing outer diameter can be the same but the size of the bolt going through the bushing is where the difference is. I think the older subframes used a slightly larger in diameter bolt but not 100% on if it was the older or newer with the larger bolt. If you get the wrong ones, the bolt will not fit through the sleeve in the bushing. Take your bolts for the lower control arm with you to the autoparts store and check them with the bushing. I believe there may also be different size outer diameter sizes also. It takes some trial and error when you do not know the year.
