need a lil advice of struts

[discokid]

So guys, I need some advice... im looking at a sheet of 6061 3/8 aluminum. Im lookin at my lathe at my shop. Im thinking of making my own top hats and coilovers. I was looking at using r32 gtr and gtst coilovers (using the correct combo)for my z cuz I hear they have a longer stroke too. But I cant find separate fronts and rears. So, back to me in my shop. Springs I can find but struts I can only find tokicos and kyb's. Is there a way that I could source tein adjustable struts or something equivalent?
