I don't remember the dimensions of the ones that I made but I can figure it out with the GC spacers that I have. I will make some out of aluminum if there is interest. I am not a vendor here so I am not selling anything "yet". I have a really nice set of spacers(MM influenced) that I am making for my car right now and I am sure there will be interest in those. I will become a vendor once I get my toe rods, trailing arms, rear spacers, and motor mounts completed.
