would the struts and strut mounts on a mk4 supra fit on a 93 sc400? if so.. what is the difference between supra ones vs the stock ones on the sc400?

 

Yeah, it should fit. I believe the only difference between the supra and sc is where the spring sits on the shock. I think Inner Diameter of the supra springs are smaller than the ID of an SC spring or its the other way around (it's been a few years since I've had a SC and supra setup side by side to compare).

The only thing to remember is that you want to use complete assemblies from either a supra or a SC. Mixing and matching will not work.
